The above is really useful but I am still confused with some of the settings and performance options for ATI cards. Is the Config.ini file the determining factor on graphics and performance?
Also, the IL2 set up menu has a number of checkboxes and if these are checked incorrectly will there be conflicts with the .ini file? e.g, I thought Arbmultiexture be checked only if using S3TC compression and what should the other options be set at?
Then there is the ATI Catalyst 3D settings (which confuses me even more). Should these be checked to let the application decide or should the sliders be set to a particular position? I noticed that I get frame tearing but this disappears if I force vertical Sync to ON but this then seems to reduce FPS.
In a nutshell, where do you start with determining the best compromise between FPS and optimised graphics for ATI cards given that there is a setup menu, the catalyst Control Centre and the Config.ini. A 'duffers guide' and 'stickied' would be a great idea........
