Not everything a driver does is accelerated. They tend to accelerate common
scenarios. It is just that as of Wine 1.1.31 we delegate more tasks to XRender
and likely hit some stuff which the Nvidia drivers don't accelerate.

Open dlls/winex11.drv/xrender.c and look for 'BOOL
X11DRV_XRender_SetPhysBitmapDepth(X_PHYSBITMAP *physBitmap, const DIBSECTION
*dib)
'
add the following line (below 'ColorShifts shifts;'):
return FALSE;

Then recompile and try again. Likely it is fast again then (it just disables
the new code).

Does the issue also occur on Powerpoint 2003 viewer?
