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.
As rdr09 has stated i have a very similar rig to you so i'll see what happens on my end.
In Crysis 3 i'm using High settings at 1080p, MSAA x4 and AF x 8 and i'm getting about 45-50fps average in the first mission (The most Rig intensive imo) with dips to 30 fps with only ONE 290 being utilized, Crossfire didn't enable for some reason.
I'll Edit this post with Far Cry 3 results and with Crossfire Crysis if i get it working.
EDIT: got Crossfire working, CCC disabled it for some reason
Same Mission, Same settings, avg 80-90fps with dips to 60fps and CPU was hovering around 85% usage (running 4.74Ghz atm)
So this is looking like the CPU and Ram is holding you back a little, I'll Boot into my 5Ghz profile and see what happens then,
It's worth noting that so long as you keep the temps under 65c the Vishera Chips will handle it
EDIT2: I'm getting roughly the same fps as you in Far Cry 3, I've got it set to Ultra High with MSAA x 4.
it's barely utilizing one GPU, it's seems Far Cry hits a CPU limitation hard early on
Will try it at a higher CPU Clock.
Final Edit: Well, my 5Ghz profile is giving me all sorts of grief atm for some reason, But from everything i've seen so far best pieces of advice i can give is
- set your ram back to 1600Mhz,
- run it as a single card system,
- don't play Far Cry 3
- or you can fork out some more cash for a 4770k and Mobo.
harsh but true, there might be something i'm missing here though, there are more experienced Vishera owners out there than me Edited by Sgt Bilko - 3/11/14 at 2:19am
