What's the purpose of the upgrade from 2500K to 3770K? Performance improvement from the CPU change alone won't improve game performance all that much.

As for reaching 4.5Ghz on a 3770K on air, that's very achievable without a delid. What's your cooler?

Nice work!

Just keep on eye on temperatures with that cooler. It's not quite up to the grade of the Hyper 212 Evo I mentioned to you (Hyper 212 has more heatpipes and a larger/better and probably quieter fan on it), but so long is it's working for you then that's great.

Get rid of that stock heatsink and put in a decent aftermarket one, something like a cheap Coolermaster Hyper 212 Evo would do the trick.

The stock heatsink is only just acceptable for running that CPU at stock speeds, you really shouldn't be overclocking on it.

Throw in a cooler like the one I mentioned above and you're temps at stock speeds will come down and it will also give you more overclocking headroom. You can spend as much or as little as you like, but the Hyper 212 Evo is probably the best budget cooler.

As for your performance, yo're talking about a detailed addon airport with fairly high levels of AI aircraft, so what you're describing is not really out of the ordinary. If you want more FPS you can either overclock higher, or otherwise you need to drop back on some AI or some of the detail at UK2000 Gatwick. You'll probably see more benefit from dropping back your settings.

I can't imagine a Titan outperforming a GTX780, after reading a lot about GPU's lately. Yes, the Titan has more VRAM but how much is actually used? The raw power of the GTX780 is simply higher and more VRAM won't make such a huge difference, at least not that it would have no problems in the situation you described.

Just to point out it's the GTX 780Ti which has more raw horsepower than the Titan but with half the Vram.

The GTX 780 (non Ti), is very marginally less powerful than the titan and with half the Vram. However performance wise in most games the difference is virtually negligible and with a very slight overclock the 780 beats a titan quite easily.

That's not at all what I was saying though Noel. The OP was saying there is basically no improvement from a 2600K to a 4770K, which simply put, is not true. The improvement can be quite noticeable in FSX. Perhaps not in other games, but FSX is it's own beast.

A 5.2gHZ 2600k would be quicker than a 4Ghz 4770K. It would be more like 4.5-4.6Ghz on the 4770K.

His numbers may have been off, but what he was saying is correct.

So, my GTX780 will boost in FSX when it needs to, without using K-boost, when demanding situations occur. But, a lot of the time, it's pretty much overkill for FSX and sits at its base clock.

Thanks for trying it out for me. Confirms my observations as well. I was initially concerned my GPU wasn't boosting where it should be.  :good:

How'd the floors turn out?

Oh nice.. then mine should improve by maybe as much as 7-8 fps i would think.

 

Did you Delid your cpu to make it cooler.. or just went as is?  Which cooler do you use.. i'm thinking ill just give the 80i a shot and not delid for now (and hope i get a good chip in the lottery of overclocking).. 

 

also have you run Passmarks cpumark on that by chance?

No I haven't delidded. Not really interested in going down that path to be honest. I'm running a H110 and temps when gaming peak at 60*C. That's the hottest I've seen it get unless stress testing.

Sorry, haven't run cpu mark or anything like that.

That is not correct.

As I wrote above adding a second GTX680 to my current system and using them in SLI gave me 40% more fps in the 2d cockpit and in spotplane view.

 

Also the extra performance gain with a 4770k compared to a 2600k is minimal.

Did you use the same type / speed of memory ?

Were the mobo's the same quality ?

Tweaks ? Etc.

Your situation may be unique since you're not using the VC, but probably 95% of people do use the VC, so not sure about that one.

But my performance when SLI is enabled on my 780's is actually worse than running in single card config.

I have tested same RAM/Faster RAM the works. Mobos were of comparable quality and settings in FSX/Tweaks you name it were all identical. 4770K came out on top time and time again.

I don't mind admitting when I'm wrong, but in this situation the results spoke for themselves.

Westman has done considerable testing across all his systems as he's mentioned and his results are in line with mine also.

If both are tested on a fresh install than indeed it is correct.

 

But who would reinstall Windows , needed programs , then FSX and then test it with FSXMark11 on a system already running FSX ....and then start rebuilding a newer system and do all that work all over again... ? ? ...

 

If the 4770k in 8 games is only 1-2% faster than the 2600k than suddenly in FSX you will not get a lot of fps extra...

Well for me testing was completed straight after new builds/fresh windows install etc and 4770K comes out on top without a doubt.

Other games are not as CPU hungry as FSX and depend more on the GPU, this is the reason you don't see much difference in other games as it's more about the GPU there.

In FXSMark11 topic pc's with a 2500/2600/2700k already running FSX for years are being compared to updated pc's running FSX just for a few days/weeks/months.

 

Every time you reinstall FSX it runs smoother because less addons are installed in the beginning. Over the time being extra addons for FSX and mostly also other software is being installed and bit by bit the performance drops...

Sorry but that's actually incorrect so long as FSXMark 11 is run properly as per the instructions. It should be done on a fresh install of FSX with identical settings used across systems.

Mine was run on fresh installs with instructions followed to the T for both my 2600K and 4770K. My 4.5Ghz 4770K outperforms my 4.9Ghz 2600K.

Just FYI, my 4.5Ghz 4770K is yielding better results than my 4.9Ghz 2600K. The average improvement was about 5FPS if I recall correctly, so there is benefit but it's up to you whether it's worth it to you.

4770K does have some other benefits such as supporting pcie3.0 as well as more native SATA 6GB/s and USB3 ports.

Running dual GPU's in SLI is not currently of much benefit to FSX.

Will P3D v2.0 take advantage of SLI at release and if not is this likely to be implemented at a later date?

Well sure, but it could also be a waste of $60.  After all the money and tweaks I've put into FSX I have finally got it running very well and stable.  Only time will tell, I suppose.

Isn't LM's refund policy 60 days, so within that 60 days if it's not for you then you con obtain a full refund.

You can always try it out and make use of that if it's not for you.

Gave it a shot and in both cases my numbers were about the same.. still.. point taken



I've tried OC'n video cards and even the 670FTW before.. never saw a real change in fps for fsx anyway.

I just recently tried overclocking my 780 and in testing the average FPS in FSX increased by about 2FPS. So whilst not mind blowing it can make a difference, and the little 1-2FPS from here, there and everywhere all add up.

This was tested using the FSXMark11 test flight plan with the average calculated based on the last 4 flights out of 5 flights conducted (the first flight you load in FSX will always have lower FPS due to tecture loading etc, so this result gets discarded)

Worth noting but I do run the EVGA Precision software during testing.. trying to keep the 670 and 780 at 70C or less to prevent throttling and the 780ti at 83C or less all using the fan/temperature curve settings.

Don't hold the 780 back to a lower temperature like 70C, by doing that you're likely limiting the performance it's going to give you in the sim and not letting it stretch it's legs so to speak.

If you're letting the 780ti max out at it's throttle point of 83C, then let the 670 and 780 go to their throttle points too so you can get a more fair and accurate representation of the results. Otherwise your results may be skewed.

Hell, you can let the 780 run up to 90-95C if you're keen on overclocking. Not suggesting you do this though. lol. If I'm overclocking my 780 I set my temp target at about 84C and have no throttling whatsoever.

Just my 2c.

Also, don't forget about fan profiles. These can impact things too. If you make a change on one card, make the same change on the other.

Oh ok, I was a bit confused there.

thanks for clarifying that yours is doing the same as mine.

Correction! Mine is boosting also to full power, I've played BF4 and indeed the GPU got  unleashed, I have forget to unlock to 1225Mhz, that's why it was running just 1150mhz! 

Yes, I'm using FPS locked at 30 and 1/2 vsync in FSX

Thanks for clarifying. Perhaps my 780 isn't boosting in FSX like yours does because the 780 is a stronger GPU. Guess I'll wait and see what SAAB340 finds when he tests his out.

Cheers!

Ahhh, Gentlemen! Sorry to jump in.

 

 

Isn't it an old wisdom that FSX is mainly CPU limited? My understanding is that you can hardly bring a GTX 580 to its limits in FSX. So I am not surprised that a GTX 780 does not give you any substantial improvement on fps (over e.g. a GTX 580) and is not forced to use its turbo.

 

 

 

But I hope that this will change shortly in P3D 2.0.

 

BTW: Do you use X-Plane? Have you tested your GTX780 with X-Plane10?

On the contrary, a stronger video card will yield good performance benefits in certain situations such as running higher resolutions and will also result in less FPS drop when running higher AA levels or in heavy weather.

I agree though that hopefully P3D 2.0 will make better use of GPU's, particularly in multi-GPU setups.

No I haven't used X-Plane. Some of the videos/shots I've seen do look impressive but I don't really like the idea of the "believable" world they have, but I might take a look some time.

I've tried other games, including BF4 and BF3, the GPU is boosting, but no more than 1150Mhz, if I try benchmark programs it will increase to it's full potential!

I'm thinking that we have great GPU's and games can't reach their limit! 

Mine boosts just fine in other games and benchmarks too, it was just FSX.

What were your settings for FSX though? were FPS locked/unlocked? 1/2 vsync tweak on/off? etc. Like I said in my original post, mine would boost in FSX but only if FPS were unlimted and no vsync tweak.

LOL!

I know that look all to well! Better get that floor laid first. haha

Could I'd be because the lower framerate doesn't need the GPU to boost? That there's more than needed GPU grunt there at base clock anyway.

 

What happens if you crank up the AA settings in inspector to something insane?

That's a good point, I didn't try increasing AA levels above what they already are, however I didn't have "Usepools=0" set in my FSX config and did try using that to put more load on the GPU but there was still no use of boost clock.

Apparently there are other games out there which also have this same problem. I was reading a thread elsewehere and someone mentioned "League of Legends" (which I've never played) experiencing the same thing.

I think I read in another thread you also have a GTX 780? Would you mind testing out to see if your GPU is using it's boost clock under the scenarios I mentioned?

Found it, but it doesn't make any difference. Thx! 

Mine it's boosting to 1150 in FSX and in other games to 1250.

Are you running unlimited FPS, 1/2 vsync tweak etc as I mentioned in my first post?

It's called K-Boost and it's in the same area where you can increase voltage.

So just this last couple of days I've been tinkering with overclocking my GTX 780's using EVGA precision X to squeeze some extra performance out of them.

So far as FSX my overclocking results on the cards (not running in SLI for FSX) yielded an average performance improvement of about 2FPS.

What I noticed during the course of my testing though was that the GPU would run at it's full boost clock as long as FPS were set to unlimited and there was no 1/2 refresh rate/fps limits set in Nvidia Inspector. Monitoring was done using GPU-Z.

However, as soon either 1/2 refresh rate was set or an FPS limit (internal or nvidia inspector) the GPU would fail to run at its boost clock. this was regardless of if the card was at it's overclocked or stock settings.

There is however a setting in EVGA Precision X  that will force the card to run at it's full boost clock, allowing you to get maximum performance out of your card for FSX or other games/apps that don't seem to boost.

I just thought I'd throw this out there and see if anyone else had noticed their cards not boosting in FSX and as a bit of a heads up that this may help give a little extra performance out of your card.

Cheers!  :good:
