--- Comment #42 from Lex stallman2013@gmail.com --- Hello! Yes, I have bad performance, lags, lower than expected frame rate in Unreal Tournament 3. In recent wine 2.8. When I'm looking on simple wall frame rate is 60, but when on scenery with detailed objects across map, like Deck, fps lowers to 15-18 and cpu loading becomes 200%
I tried to compile wine 1.7 from source, with -o3 -m native optimisations, apply Stefan patches from https://www.winehq.org/pipermail/wine-devel/2013-September/101106.html and this definitely helps. After that minimal fps drop is 25-30 on Deck ut3 level. This helps, but still not solves problem for 100%. AFAIK this could be Unreal Engine 3 bug itself, many ue3 gamers reported same issue on windows.
