I have been having an issue with my new 7950 and assassin's creed 3. While outside I usually get between 22 and 34 fps, and my gpu is only at about 20-40% usage. So that leads me to believe that I should be getting 40-60fps. So my question is why wouldn't it be getting higher fps? And how can I solve it? Also, in cut scenes it gets higher fps and I get 70%+ usage at these points. It's only this game as also. In metro I am getting 40-55 usually. I played it for about 30 minutes today and it didn't drop below 40 once. On borderlands 2 it was getting about 100-130fps. So I can tell it isn't an gpu issue. I don't understand what going on. Why won't my gpu have a higher percent usage on that game? With those games it also is getting a much higher % usage.
Would thinks its an optimization or driver issue rather than a hardware thing. Download the latest Catalyst and AC3 patches, if that doesn't fix the problem then you may just have to wait until Ubisoft/AMD fix it.
Ubisoft had better lift their game if they want any love from PC gamers.
