Before I upgraded to this 1080ti, I was running a 980ti, overclocked, and she had no issues running this game at high settings with occasional dips to 55fps, but this 1080ti, with the same preset, is dropping to 40s.
980ti, high settings, 720p - 4k, city areas, drops to 50's
1080ti, high settings, 720p - 4k, city areas, drops to 40's
Same cpu speed for both cards. 1080ti has an aggressive fan curve so doesn't run past 70c in gameplay.
I messed around with the graphics in Forza and resolutions, running at stock (1440p) and pushing it up to 4k and down to 720p, there is minimal difference in fps for those areas affected in gameplay. I also cranked Forza to ultra and the fps doesn't move much. What's worrying is, 1080ti usage sits below 70 per cent, and downclocks itself as it's not being fully utilized.
Even running Forza 3 on low preset i get fps dips under 60fps with the 1080ti @ 1440p.
I've tried a few things people have mentioned, such as, disabling cores, priority etc to no avail.
I've reinstalled the latest driver countless times using ddu [setup as a clean card in safe mode] so I'm not seeing a driver issue I don't think.
Is the 4770k @ 4.2ghz to blame? Is it not playing nicely with the 1080ti?
