Hello,
I have two questions regarding GapiDraw 2.05 performance:
1. I use BltFast, and performance drops significally even on stationary PC (abnormally, maybe about 60%) if I use Opacity (GDBLTFAST_KEYSRC | GDBLTFAST_OPACITY). It happens even if I use very small surfaces. If I just turn off GDBLTFAST_OPACITY performance is good again. What am I doing wrong? Does GapiDraw use hardware acceleration for opacity, because I worked in Direct3D and giving opacity to textures on accelerated hardware almost does not affect performance?
2. On PPC performance drops from 30 fps to 12 fps when I start to move stylus, when I stop using it performance returns to 30 fps. This happens even if I dont do anything OnStylusMove. Is there any workaround or this is PPC problem?
Thanks in advance!
