Sketchy config

[pibuz]

Hi all guys! Sorry to bother for what can seem a silly request..
I've recently updated my video card from a 9800GTS to a GTX480, all nVidia.
Strangely, the new video card seem to handle sketch models in a worse way: textures are refreshed with a little delay, the model becomes quite heavy in the turn of 5/8 MB...I guess this is something library-related: Sketchy uses openGL, the GTX480 is based on directX and CUDA chip...
Is there a way to fix this? It is so bothering that having a much better graphic card produces a worse result!

Thank you a lot for reading!

All these cards should support OpenGL nowadays. Have you updated the driver? (With what they generally come in the box is mostly some really old, outdated ones).

I had some other minor conflicts with the embedded drivers, so I recently updated EVERYTHING in my pc. Now I have the latest for almost all my software and hardware, both drivers and software version
