I go in the game and usually have 200 300 fps but when I just shot low to 40-50 fps with many breaks and alterrevolution client does not have this problem.

 

 

PS: i have my graphic card drivers updated.

Check vsync and others

 

do this to console

exec config_mp ; vid_restart

vysnc is not enabled, others like what

 

i put exec config_mp;vid_restart doesnt change anything... problem stays

then problems not game setting related, probably some ati-nvidia cards using application profiles which is improves performance... they using these profiles with application executable iw4mp.exe...

 

try renaming iw4m.exe to iw4mp.exe and run it...
