Upgrade to GTX670 from GTX560

Recommended Posts

Hey all

 

Just upgraded my older 560 for an EVGA FTW GTX670. Strangely there has been very little performance increase. Reinstalled drivers but am still getting about only 10-15 fps in clouds (4096 REX) at addon scenery airports, only 2-3 fps increase if that.

 

I5 2500k oc 4.5ghz, 8gb 1600mhz, running fsx off ssd by itself.

 

Thanks!

Not surprising Seth, FSX is much more CPU hungry than GPU hungry. I would be surprised if you noticed any difference at all.

FSX doesn't really care that much about your graphics card as long as its decent, I had GTX 550 before and went from it to Radeon 6990, however didn't notice much increase (though I didn't buy 6990 for FSX but for other programs that can make use of it).

So are you saying that what will improve my performance now is basically an i7?

Just very interested in the whole idea. I hear that people who upgrade from a 560 to a 670 have frames jump from where they were 15 before to smooth flight - albeit only in certain extremely graphics intensive spots ie multiple HD cloud layers, photoscenery, and especially when using bufferpools=0 as I am.

 

All opinions are greatly appreciated! :-)

Yes. FSX is "CPU bound", but having a strong GPU does help when using high visual IQ settings.

 

I'm hearing a lot of "the GPU doesn't matter" around here lately. That's not true when you are concerned with visual quality. Think: High anti-aliasing settings, HD Clouds, dense autogen, high resolution, etc.

With this system in my profile, I went from a GTX 460 to a 560. The difference was noticeable with my AA settings and supersampling.

Video Card and FPS is not highly correleated. Meaning.. Improving on Video card doesn't mean you are going to get FPS in FSX.

 

But that does not mean getting a better video card is not going to have benefits. It does.

 

For FPS, your primary focus is your CPU and OCing. along with fast memory to a small degree.

 

The benefits of a good video card is in your ability to use bigger and multi monitors with high AA and what not. Also bigger Vido memory also helps a lot.

 

For me, I have have the 670 and I have connected three 24" monitor in wideview + a 4th 19" touch screen monitor. I have AA turned on. I don't run inti VRAM issues.

And that is where I feel something's gone wrong as I have had no such significant improvement. Perhaps I was expecting too much from the upgrade but if anything my FSX looks worse. It's like there's too much sharpening of the image and therefore it's pixellated - chunky ground textures I never saw with the 560 etc.

 

Thanks!!

Sounds like you may need to use Nvidia Inspector and set your image IQ settings again. New drivers will overwrite the profile to default. In FSX , you want AA off and the AA controlled on the driver level. Head over to the PMDG General Forum and look for Ryan's sticky regarding profile settings in Inspector.

This is all done, profile is checked and everything is set according to the sticky (plus 2x sgss) - no effect.

 

AA is off in FSX.

 

Appreciatively,

Something's amiss. No behavior flag set? That's important. No DX10 preview?

Behaviour flag? Can you elaborate?

 

DX10 preview set off - is this ok?

 

Thanks again!!

Under the MS Flight Simulator X profile in Inspector, in the "Antialiasing" section, there's a SettingID labeled "Antialiasing - Behavior Flags". The SettingValue should be set to "None".

Sorry, yes, that setting is set to none.

Just making sure...

When major system changes are detected, FSX can automatically set its screen resolution to funky low values. I spent an afternoon once chasing something like you describe when it turned out to be this problem.

 

As mentioned, a better GPU won't compensate for most heavy duty slider settings and saturated add ons; the AA/AF eye candy is where the pay off is (and how sweet it is).

The CPU/memory/cache determines how many frames per second (FPS) can be generated by the internal code running in one or many cores (processing units) and accessing data and instructions located in cache or memory (lets hope you never get in a paged situation where FSX waits for something paged out to a real disk).

 

The GPU can only process data sent to it by the cores running FSX/Windows code. Some of that data may be PhysX requests but mostly the data sent to the GPU is to be displayed.

 

It appears that most video cards with a Passmark video score of greater than 2600 - 2750 (GTX 560 or so) can stay ahead of the data sent to them by even the fastest overclocked i7 at some moderately acceptable level of visual quality (AA, IQ...etc). Thus the FPS rate is, at that level of visual quality, limited by the CPU/cache/memory ability to generate frames to display (data sent to the GPU).

 

However, a faster GPU, one with more memory, or more processing units can deliver the SAME FPS (limited by the CPU...etc) but at stunningly higher levels of visual quality.

 

It is possible to decrease the FPS displayed on the monitor(s) by dramatically increasing the specified visual quality on a less capable GPU. It that case the CPU might not generate it's maximum potential FPS rate while waiting for the GPU.

 

Thus we say that FSX frame rate, is for the most part, limited by the CPU complex and primarily the core clock speed.

Try rebuilding your fsx.cfg file and doing all the tweaks again, after seeing what default is like. You won't really see huge FPS increases but you should definitely see a smoother flight.

Okay thank you everyone your replies were all extremely informative and helpful, I have found a few sliders to tweak, and kudos to the person who mentioned the resolution - it had reset back to 1024x768.

 

Thanks again,
