texture filtering trilinear optimization on or off

To have consistent results you can load any of your WEGO save game replay. In order to see actual FPS in game install free program called FRAPS (google search for it - it comes with no spam). Please do report here if you checked it out.

If you do I'm glad I helped you get a better performance out of your machine in this game. I'm interested to learn if any other owners of Nvidia GPU would get the same surprising result. I have Geforce 550Ti MSI GPU with the (at the moment of this writing) latest 314.07 WHQL Drivers. Very different things, as obviously we can't change any of that, AND it's not necessarily long-term relevant to your (or others', if they see your results and buy your card) card's performance with CM. Panel settings have nothing to do with Combat Mission - you're just forcing your card to use those settings while rendering Combat Mission. So when using different control panel settings you're really measuring card and driver performance more than Combat Mission performance (case in point, Hister's 16xCSAA performance, which is entirely down to his drivers and has nothing to do with anything CM is doing). Performance of control panel settings will change, irrespective of Combat Mission, with new driver releases. It looks like higher-level CSAA is probably the most heavily optimized path for your card. We don't directly affect or support any of this (nor do we need to), it's down to how your drivers interact with OpenGL. Right now you're likely looking at differences in driver optimization.
