Dear all,
i have no idea why my computer can not handle the game as expected.

My PC: i2500K running at 4.4 Ghz, 16 GB Ram, Geforce GTX 980Ti on a G-Sync monitor with WQHD resolution.

Problem: WOFF UE sometimes runs smooth in 2560x1440 with 90-100 fps. In most cases (quick fights or campaign) im stuck to 15 fps (!). On the ground, when starting, when flying, when landing.
When i change resolution to 1920x1080, it is more or less all the time stable on 60-80 fps.

I can not tab out to windows while playing, so i can not see the CPU or GPU usage.

Thoughts and facts:
- All my drivers are up to date.
- Game starts in Win8 compatibility mode.
- I play other sims and gameslike FSX, DCS, Sturmovik, Battlefield 1, World of Tanks, Crysis, Far Cry etc most of the newest games in 2560x1440 with high or even ultra settings with around 60-120 fps. This leads to my conclusion that there is no general heat or frequency problem with my computer. I have absolutely no other issues with my pc.
- I reinstalled Directx 9, all settings on high, Antialiasing 2x
- I can not reconstruct why sometimes WOFF runs ultra smooth in 2560x1440, sometimes not. In FullHD its always smooth.
- I tried to override the game settings with nvidia settings, with no success.

Has somebody more ideas what to try?

Thank you
Jan
