Struggling with performance

post #1 of 76
Thread Starter 
Hi all,

I'm getting a bit frustrated here. I've recently completed a build and it's just not performing as well as I had hoped.
The main things I'm seeing big problems with are Crysis 3 and Far Cry 3. I'm aware both are demanding games but wanted to check if others have the same experience as me or if I'm doing something wrong.

My build is as follows:

FX 8350 - 4.8ghz on water (50C in game)
2x MSI R9 290 Twin Frozr Crossfired (85ish in game each)
990 Sabertooth v2 motherboard
12GB of 1600mhz RAM (2x2gb of Ripjaws and 2x4gb of Corsair Vengeance) - these get set as 1333mhz by bios
Samsung 840 Pro SSD 128GB.

In Crysis 3 I can see up to 120fps but then I see dips to 20 fps. It's hard to give an average as it is so wildly variable but I'd guess the average was 45fps. All settings on high - I've messed about with settings and even changing a whole lot of settings to low seems to yield little improvement.

This cutscene here shows an r9 290 in Crysis at 1080p running between 50-60fps (29 seconds in to about 1:29). I have repeated this test and have dual r9 290s that are overclocked and not hitting their thermal limit as they're non-ref but I'm seeing lower frames 20-40)

Far Cry 3 - fairly similar story. Average framerate is probably around 40fps. Variance is less extreme but there's repeated lag. If I stand on the spot and spin around looking up at some trees I get constant hitching and dipping from 80fps to very low (FRAPS doesn't seem to change to reflect it). Changing settings has minimal effect here as well.

I feel like I was getting a more solid performance on my old rig which was with an i7 920. By solid I don't mean better, just less variable.

Perhaps I'm just going crazy? Is there anything obvious I might have wrong that's causing these problems? Am I expecting too much from my setup?

BIOS/GPU drivers are up to date.
3DMark testing shows I'm 'better than 92%' of testers. I feel that with results like that I shouldn't be constantly niggled by frame dips etc.

Everything is being played at 1080p.

Thanks in advance and I hope this is the right forum - I've posted here as I think it's more likely a CPU issue than GPU.

Far cry 3 has dips. I wouldn't call it the most optimized game for sure but I dnt see why it would dip that low with your gear. Far cry 3 is a modded crytek engine so it should be similar to your crysis 3.



Have you tried setting the cpu to stock settings and check fps ?

also when you disable crossfire does the dips go away ?

Have you tried using a single card just to make sure it isn't a crossfire issue?

Thanks for the swift responses. I have tried with the bios at default and with just the one card but the problem persists.

CORRECTION: The big hitches in Far Cry are resolved. Frame rate is the same as in SLI so I'm guessing SLI is really not happy with FC3.

Having researched online I'm seeing Crossfire resulting in near 100% FPS improvements in FC3. I'm either doing something very wrong or have some dodgy drivers. I'll do a full clean of them tonight and see where that gets me.

when i had my 7970 FC3 crucified my card at ultimate settings with 2 msaa let alone going 4 or higher biggrin.gif

not the best optimized game but one of my favorites and yet too finish when i get another super card thumb.gif

Run 3dMard Firestrike and show us your results. We can compare with other people that have a similar set up. You have solid gear and should definitely be getting better performance.

http://www.3dmark.com/fs/1841560 Doesn't look like there's any problems here.
Note that's with 8GB of RAM as I recently removed the mismatched sticks to see if there was any difference (there wasn't).

What`s the gpu usage?
post #10 of 76
seems a crossfire issue, remember anyway that cryengine is nvidia biased/optimized so beware of games like crysis/fc
