Medal of honor doesn't even launches!

As far as I know, stealth 3 s540 doesn’t supports the openGL. Everytime i open the medal of honor, it crashes and the windows video configurations get weird. I can’t even enter the game options screen! What should I DO???

View the “Readme.txt” file that came with the game. It specifically states that the game is not supported to run on your video card.

From the MOHAA Readme.txt file:

These older cards yield a frame rate that is often
below 10 frames per second even at the lowest video
settings.
-PowerVR NEON 250 cards:
Video Logic PowerVR Neon 250
-S3 Savage 2000 cards:
Diamond Viper II
-S3 Savage 4 cards:
Diamond Stealth III S540
Diamond Stealth III S540 Extreme

-SiS 300 cards

The only option you have is to upgrade your video card, sorry.
