Some quick things about this game (more about the engine actually):
- V-Sync functions in a weird way. Disabling it caps the FPS to 60, otherwise it's uncapped. Since I have a G-SYNC monitor I just leave V-Sync on to uncap it (although it can be uncapped in My Documents\My Games\soma\main\user_name_settings.cfg) since G-SYNC overrides in-game V-Sync anyway.
- Instructions for disabling the crosshair can be found here, but this didn't work for me.
- The only AA method is FXAA and it's highly ineffective as expected.
- I have not found functioning AA bits for this game. 0x0000F0C1 does not work.
Added this and more to the first post.
