Oh this is a definitive limit, I would appreciate 3d acceleration to speedup everyday apps, and not some small 3d games, this is secondary for the freerunner actually. > > *) when necessary you can use directly Xlib because X is 2d accelerated ? > > you ALWAYS use xlib* - if you want to interact with x in any way. I mean, if my preferred toolkit does not advantages of hardware acceleration, I may use Xlib and call for example XCopyArea to do fast blits in video memory? I wrote a small code snippet to test XCopyArea performance, and it seems to do about 25fps smoothscrolling but at the cost of XGlamo using 70/80% of CPU. This seems very strange, it maybe my code is wrong (I repeat I'm not an expert :) ), or XCopyArea is not full accelerated, or Xglamo has to be optimized, or that the Glamo GPU is simply slow :) Regards Nicola
