Hi,My system:Athlon XP 2000+768 ram DDR266GF4ti4200 128mbSettings in driver 41.09:1280x1024x32Antialiasing OFF (I found the performance is greatly improved without AA, from 20 fps to 50 fps)Anisotorpic Filtering 4x (I lost performance here, but no blurs)Texture Sharpening ONNow what is: Performance: Application, Ballanced or Agressive ?My system is running fine, frame-rate is good, but I think the simulation smoothness should be better...in the above configuration I can't see much difference with AA on or off in terrain textures.What do you think ? What do you use ?Thanks,Ulisses

I use application, but I'd be interested to know what others use.

I couldn't find any difference....anyone ?thanks,ulisses

Keep in mind that with Texture Sharpening ON, you are really running with Anisotropic Filtering set to 8x, not 4x - which is likely why your performance is weak.Leave your performance setting at Balanced. I haven't seen any improvements with setting this slider to Aggressive - I have seen some problems.J

got it....thanks.ulisses
