Shall I get the GTX 680 or not?

Recommended Posts

Can a GTX680 user please answer me and Arjen's question? How does the 680 compare to the 580 when it comes to FSX performance?

The 6xx is indeed a revolution for the fact that you don't need tripleheadtogo. PERIOD!

OF course if you are not into multi monitor setup.. then ....whatever! :Just Kidding:

OK, thanks. But as asked in my previous question: how does it compare to the GTX 580? You said that it wasn't impressive, but what's the actual difference? Is it a slight performance drop, does it perform equal, or is there a slight increase? Thanks in advance. :smile:

 

Overall the 680 performs better than my 580. FPS are almost similar but the 680 appears to run smoother and without any stutters.

 

Overall the 680 is an improvement over the 580, while a small improvement it is still a better performing card.

 

If Nvidia changed a 580 to a 1080. Everyone would want one. it is, for the most part, a bigger number better MARKETING scheme. If I had a reason to be buying new I would go with the newest but I certainly wouldn't pay $ to upgrade. A 680 is last yrs 580 . 2011 Mustang compared to a 2012, small cosmetic changes derived from a marketing standpoint to boost sales.

 

Wow are you wrong.

Thanks John! This was the info I was looking for, I will go with the 680 then. :smile:

 

Do you have the default EVGA version or the superclocked version? Just wondering if I should go with the SC version or not. :smile:

I have the vanilla (02G-P4-2680-KR) 680. It was the only EVGA 680 listed on Newegg when I ordered in March.

 

Mine boosts around the same as the SC card my friend has but I had to do more tweaking initially. The SC's cooler looks identical to my ref cooler.

 

The only model I might have purchased instead of my vanilla would be the signature edition.

Thanks John for this input, this made me too decide to return my 580 and replace it with a 680 instead. Figured I don't upgrade my hardware that often so now when I'm doing it why don't go all the way. For the very same reason I also bought 2 new Intel 520 series SSDs today to replace my old first generation X25-M SSDs, I'm using SSDs for my system disk and my FSX disk.

 

This new rig where I from start planned to only get a new CPU and motherboard is now starting to get expensive so I do hope FSX will literally fly on it :wink:

Hi guys for what its worth.

 

I just put a 680 4g in and ditched my 590 (2x 580s).

 

I run 3 X 30in screens in NV surround and I have not changed any settings since doing Costa's tweak.

 

Surprisingly the 680 has produced a lot of stutters and dropped the FPS down a bit. It maybe because the drivers are a little premature for the 680. I have only tried the 301.24 drivers for both cards so I might try the original 680 drivers.

 

I tried the new card because I've read that the SLI side of the 590 can impair FSX.

 

At this stage the 680 compared to the 590 is a step down

 

 

found this quote from the NVIDIA forum today:

 

The VSYNC minor stutter bug in the Geforce GTX 600 series GPUs is a known issue and will be fixed in a future driver.

This is so annoying, cuz I'm only getting conflicting information. John says taht a GTX 680 is slightly smoother, and you say that it creates more stuttering. So as I understand correctly, you applied Word Not Allowed's adaptive VSync tweak, which should reduce stuttering, and it actually increased it? So what happens when you turn VSync off? What's your other pc specs? Maybe it's because you're using multiple monitors?

Very annoying, I found that with the 590 it was handling the 3 screens well and keeping the fps locked at 30 until I was at high demanding airports like FSDT KLAX in the NGX, then the rates would drop which is not good for stutters using Word Not Allowed's tweak. Any other setting other than 1/2 VS is worse. With the 590 Word Not Allowed's tweak was a dream come true as it removed all stutters when in the air and most airports other than the biggies. The 680 gives me stutters even when the frames at stuck on 30.

 

I'm lead to believe its the drivers from whats being said over at the nvidia forum. They have released today a new driver 301.42 & 302.59 beta which I will try now and report back.

Thanks! I hope you can report back soon. I'm starting to doubt about the GTX 680 again. However, I read on the internet that NVIDIA admitted that there's a stutter problem with their 600 cards and 300 drivers. Question is, will the newer drivers also fix this in FSX? I wouldn't be so sure...

Haven't had the time to install FSX yet and try my new rig out including the 680 but will report back as soon as I have.

Single monitor running FSXMark 11 w/GTX 680 PCI-e 3.0 x16 on an Ivy Bridge Z77 platform and 301.24 driver (not the latest .42) is stutter-free. The stutters reported by iceman are due to either a Vsync issue or multi-monitor, not strictly the driver. Or rather, the condition which may be caused by the driver is not apparent when testing FSXMark 11. I'll post results of the 680 in multi-monitor once I get my other two 1440P monitors. Will of course try out the new drivers as well.

Ok.. no change with the new drivers .42 but Nvidia have said on their website that they wont have a fix for 680 stutters until June. What I'm seeing is smooth flying even when FPS drop well below 30 in straight and level flying until I turn including on the ground then the stutters are shocken. It makes no difference if I'm in a default or NGX AC. For some reason the FPS go up and down dramatically when turning left or right.

 

Having said all that the 680 so far has fixed my main issue that I had with the 590 on multiscreens, which was an FSX freeze and CTD when approaching a major airport (50mi) like FSDT KLAX in the NGX. I like the eye candy stuff so I have my LOD radius at 5.5 & max airline traffic using UT2. Often I would get exited and make it past the 50mi point with the airport detail loading & about 100 odd AI aircraft at the gates but if I pan away for a few seconds then back to the airport ahead I get the dreaded freeze as the scenery reloads, I have to CTL ALT DEL to get out of it & start again. The 680 loads all this scenery instantly with just an ever so slight pause. Not sure if thats because of the 4g mem on the card helping out.

 

 

So l'm going to have to put up with the slightly lower FPS and stutters if I want a successful approach and land at these major demanding airports.

 

Noticable differences from the 590 are the graphic load times are really fast, colors brighter and distance detail clearer. I have not tried the original drivers nor the 301.40 with the inf tweak that they're talking about over on the nvidia forums to reduce stutters.

 

 

 

Hi Techguy

 

I believe you are right about the VS thing, somthing is going wrong there on the 680. I have noticed that I have less stutters when I set in NI settings to adaptive not standard, all other settings as per Word Not Allowed's tweak.

For what its worth,

 

I have managed to get the 680 to work without or with very few stutters. Of cause may not work with other setups.

 

Firstly: I've set everything up as per Word Not Allowed's tweak.

 

Secondly: I had to change the VSync to application controlled and insert the fullscreen VS tweak into the FSX CFG. Using adaptive not standard also helped removing stutters.

 

 

Obviously this setup is no longer Word Not Allowed's tweak but its a bit of a work around and gives me the highest FPS and almost no stutters until the VS problem is solved with the new drivers sometime in June. Also as stated above in my previous post, with the 680 vs 590 I now have no graphic/FSX freezes.

I have just upgraded from a GTX480 to the GTX680. Not a mind blowing FPS improvement but an improvement nevertheless. The GTX680 runs cooler and quiter but of course that is not the issue. The GTX680 will have a lot of extra head room to tolerate certain tweaks. The rest of your system is a good spec, don't bottle neck it with the GPU and remember, yes, FSX is CPU intensive but it is fast becoming very GPU intensive with some of the more recent tweaks/mods (such as BP=0) that have made the sim's graphical perform better for many.

 

Out of interest, originally using a mix of ******* and Word Not Allowed's tweaks in the fsx.cfg, was getting worse performance than the GTX480 but when starting with a clean cfg and running Kostas tweaks to the tee, this card is the business! Zero stutters, crystal clear scenery, no flashing and rock solid after several 9 hour real time flights in PMDG 744X into and out of dense airports. Still using drivers 301.10 - waiting for some positive feedback from FSX community before installing the ones released yesterday. One happy camper here.

2. Is there any stutters

3. Do you have Word Not Allowed's VSync tweak applied? If not, I would be curious to see from you what results you get.

 

Thanks! :smile:

Hi Greg,

 

Thanks for that you have given me some hope.

 

I found that in a default airplane and over somewhere small like KPSP I can hold 30FPS and Word Not Allowed's tweak works like a treat but as soon as I jump into the NGX and descend into the LAX area towards the FSDT airport the FPS are all over the place way way worse than my 590. The stutters are shocking and the sim becomes almost unflyable with FPS of around 15-28. (24-25 GTX590) Maybe something to do with the NGX gauges and new cards which has been mentioned on another post.

 

Can you test that for me if you have those addons.

Im going to go and install the 301.10 drivers and do a clean CFG so thanks for the INFO.

hi All,

 

The 301.10 drivers seem to be an improvement over the newer ones although only ever so slightly. I still get major fluctuations in FPS when in high demanding airports.

 

I dont know for sure but I'm wondering now if I was getting some sort of benefit from the SLI card (GTX590) when it comes to high resolution 3 X 30in multi screens using NV surround.

 

My conclusion using the GTX680 4g:

 

- 680 is faster at loading scenery than the 590

- Night lighting seems more brilliant (using UT & GEX) and smaller detail much more noticable (simply amazing)

- No major improvement in FPS from the 590

- Major drop in FPS when using mult screens compared to the 590

- VSync issue is a problem with the current drivers (fix coming in June according to Nvidia)

 

Using the VS tweak in the FSX.CFG & setting "application control" in NI seems to remove most of the stutters if at high demanding scenery like the NGX at FSDT airports and you're unable to keep FPS locked at 30. (Word Not Allowed's tweak)

 

In all I probably wont go back to the 590

Actual FPS difference is marginal under heavy loads (detailed 3rd party airports and add on aircraft). Perhaps 2-3 FPS. But this needs to be explained further... With my FPS locked at 30, it sits there almost all the time. Honestly, it is stuck on 30 nearly permanently. In FSX default aircraft, it never goes below 30FPS - even at dense add on airport/sceneries, whether on the ground or in the air. Zero (and I do mean zero) stutters, shimmers). Liquid smooth. Using the PMDG 744 or J41 or NGX at dense airports it does take a drop but never below around 18-20FPS which does become noticeable but the important thing is that there is no juddering or stuttering. This is with all FSX sliders set to Kostas recommendation also - most sliders on the max, except water on high 2X and cloud draw and density and AI aircraft, boats and cars on low to mid settings. I am not running DX10 / light bloom but plan to give it a try as I have not "switched" that on in several years.

 

I do have Word Not Allowed's tweaks applied and here is the important note - follow his recommendation and delete your fsx.cfg file (backing it up of course!). This is I suspect, because the v-sync settings that get applied to the fsx.cfg in ******* [bojote's] tweaking tool cause quite a significant FPS drop and severe stutters (I even experieinced sound stutters coinciding with the graphical stutters) at dense airports with heavy add on aircraft. I think it is the force fullscreen vsync=1 setting that clashes with Word Not Allowed's recommended v-sync settings. Without exception I am now running my fsx.cfg 100% in accordance with Word Not Allowed's recommendation and it really is fantastic. I am using 2x SGSS, not bothering with 4x SGSS as I can't see any difference but believe the load on the GPU is much greater. Just remember to also manually add the Allow_Shader_30 = 1 setting back to the fsx.cfg if you are running the Shader v3.0 mod by ******* (which I am). If you don't do this your graphics will be a giant mess.

 

Iceman notes that there is a known issue with v-sync (his post above) that will be fixed with the next driver in June. I'm not sure what that issue is, but I can't say I have an issue with v-sync in FSX. With Prepar3D coming alive, lets hope that the sim gets renewed attention from the nVida driver guru's and that in general, we will see tangible benefits to FSX from these future driver updates.

 

Out of interest, I am running on a single 24 inch LCD as the primary screen (1920x1080) VC and a 20 inch LCD secondary screen which I use to drag 2D panels across to - example- FMS, GPS, radio panels etc.

 

To answer Iceman's other question, yes, I do have PMDG's NGX but I have no add on sceneries for LAX / FSDT (unless you are referring to the default airport/scenery) - will be happy to try and let you know. Of course, if you are driving 3 x 30 inch panels - stuff of dreams :-) , bound to have a negative effect on FPS vs my setup.

Nice Post Greg,

 

and thanks to Word Not Allowed for making FSX enjoyable on our newer hardware. Good to see you're having good results from the 920, I ditched my 980 for a 2600K because I just couldnt get rid of the stutters, would love to try it now with this new Word Not Allowed setup.

 

Dont worry about the LAX test, I think I'm done with testing and tweaking for now which is what I seem to be doing more of these days. Its time to go flying and enjoy.
