Witcher 2 putting my CF 7970 onto its knees? - Page 15

post #141 of 144
Thread Starter 
AMD will probably never fix this. I have come to terms that AMD driver support sucks and I don't want to hope for better drivers when I know they will never come. When 7970 launched everyone said "better drivers will come next month". It has been 4 months and counting and RC11 still runs the best for CF configuration + eyefinity. I highly doubt there will be a magical driver that gets released that fixes all these issues.

I do not play with ubersampling because it just kills too much performance for a small gain in image quality. The problem is that I still dip below 60fps quite often and with GPU usage at a mere 50-60%. Come on now....

I also have stuttering in other games, like Crysis 1/2, Metro 2033, MW3 where it would be at 60fps then drop and spike and do all sorts of things to make my gameplay as rough and jerky as possible. Over exaggeration, however, it does get annoying. I stay constant 60fps 90% of the time, but that 10% of the stuttering that happens every minute is annoying, especially for $1100 GPUs playing DX9 MW3...Even with vsync off, it would be at 150fps then abruptly drop down to 80fps and straight back up in less than a second causing a jerky experience.

Weird... I haven't suffered any of the "jerkiness" you describe... maybe it only happens in eyefinity

Have you tried setting "Flip Queue" to 1? Radeonpro software lets you create a profile for games and I remember I fixed micro-stuttering on Crossfire setting "Flip Queue" down. Radeonpro doesn't support your graphics cards I think, but there was another software which did the same thing.

Someone else in another forum had same issue (even stuttered in Windows he claims) with your same cards. He claims to have fixed it by reverting to January drivers. Hope it helps.

Ah finally a thread re witcher 2. I am currently playing on ultra @ 1080p (1920x1200 would not get past open cutscene so lowered to 1080p)

I have it running on just the one card at stock and it runs nice.

Ubersamping does make a visual difference imo but you need xfire to run it.

My experience with xfire and this game without ubersampling, it runs better with one card, no need for xfire if uber is off. The fps spike and fall, random jerkyness.

With ubersampling on I overclock my cards in xfire and 60fps but still the same jerkyness and drops in fps. If AMD pulled their finger out I am pretty sure 7970s xfire can run this game with uber sampling on.
