22 I think thats because function Texture-from-pixmap. When You resize Your
23 window, it must be repainted by normal and also polygon of OpenGL must
24 be re-scaled and binded by texture. Normally this should be done in
25 graphic card GPU - by hardware. But - if I get wrong, tell me - nVidia
26 GS series is integrated card with poor performance, much less than FX/GT
27 cards. Also some vendors of board which hosts NV GPU to reduce costs
28 makes it from cheap materials and sometimes much of hardware are miss
29 (like DVI output or Composite output, some resistors etc.). Also memory
30 of card is very important - speed and error correction (something like
31 ECC) if available. I don't know if GT series have pixel shader 2.0. Try
32 google for more info's, more I can't help You.
