Hello all, I wonder if those of you experiencing the random FPS lag can check their GPU clocks to see what's going on. I have the latest drivers, and I have 295x2 and a 290 in trifire. Resolution is 4K. So, I play. The game is amazing at 60 FPS vsync (triple buffering enabled via radeonpro but that's it) and then at a random point, the frame rate will tank to 25-30. This happens at ANY stage. Nothing to do with in-game activity or scene or whatever. I stood in the car dealership once for 5 minutes doing nothing and watched the FPS go up and down like a yoyo. Initially I thought it was a vsync bug, jumping from 30-60 and back but even with vsync off it was the same. Anyway, I worked out today that 2 of my GPUs (ie both on the 295x2) were randomly going from 1040mhz to idle 300 and back again. As this happens, FPS tanks like crazy and then voila, back to 60. While this is happening the third GPU stays fine at 1040. RAM clocks on all 3 cards stay the same. It's very weird, I haven't tried single GPU performance but I doubt it'll hit 60 FPS vsync at 4K without fidelity compromise, which I really don't want because it looks damn fine when it works properly. Does anyone have any suggestions or ideas? I'd be interested to see if this replicates on other systems. PS: this happens even when radeonpro is disabled, and ULPS is off naturally.
