Thanks, i found the solution...
- In-game, press F2, config window appears
- In "Others" tab uncheck "Texture Correction"
- If problem remains uncheck also "Texture Completion" and "Voodoo2", but for me was gone only with step 2 done.
Too bad the problem pop again when trying to use antialiasing of NVIDIA panel, anyway, is better than playing in the lowest resolution and 16 bits!
Thanks all for the help.
