MATRIX 7970/280x CF in 1440/1600p - Experiences

[b3kab3ka]

Hello again, are there any other users of CF of Matrix cards 280x or 7970 in 1440p/1600p?
I'm experiencing major stuttering with Frame Pacing enabled in 13.11 V1/V3 beta drivers.
It's happening in any 3D Application every 2-3 seconds. I will try too record it and upload to youtube later.
Performance is a lot better without Frame Pacing enabled but still a little choppy.

Have anyone experienced it too? Is this famous micro stuttering in ATI setups?

Actually it slowly gets better and better in BF3 or maybe I'm getting used to Crossfire multiGPU way of working 🙂

I have no problems with stuttering what so ever(2xmatrix plat.) I always use radeon pro and the dynamic framerate control capped @60fps(no tearing). The frametimes are super solid.

And no inputlag at all like you can get with v-sync. The gameplay is much smoother with capped fps, it's rock solid @60 at all times. Feels alot jerkier when fps vary from 70-200. res @1440p

I actually managed to set everything I guess, no more tearing/stuttering. I ran 3dmark today on v6 betas and my FPS graphs looked crazy with HIGH/LOW FPS. I narrowed down what caused that - wait for it - GPU Tweak.
