Use DX9 in Steam?

[jcrox]

Can anyone tell me how to launch warhead in steam using DX9 instead of DX10?

Unfortunately for me this game for some reason runs like absolute crap in DX10... I don't get it, DX10 1920x1200 everything on high Crysis runs just fine but I can put anything above mainstream in warhead without it turning into a 3-5 fps slide show. :(

1.Go to your steam games page.
2. Right click Crysis Warhead or Crysis Wars
3. Click "Set Launch Options"
4. In the box type in "-dx9"

DX9 actually runs worse for me. I even tried the game in XP and it's very bad. So far Vista on DX10 on Gamer setting is the best I can do. Even then it gets quite bad, under 20 fps most of the time and then sometimes around 10 fps. :(

Thanks, I forgot to put the "-" in there.

I can run it @ 1920x1200 enthusiast settings DX9 now :)

Much better looking than DX10 mainstream.
