GapiDraw 1.1 beta1 issues

In using version 1.10b2, I've noticed something a little odd versus my previous use in 1.04 on a stationary PC.

I'm guessing that it may be related to hardware acceleration in some way, as it only occurs in Fullscreen mode.

Using a blt with a colorkey and scaling, the framerate drops precipitously in fullscreen mode. This is a pretty large blit, admittedly - 500x400 or so. This does not occur in windowed - everything is fine.
I tried setting the backbuffer to GDDISPLAY_BACKBUFFERSYSMEM and that fixed it as well, so, as mentioned before, I think it might have something to do with hardware accel. I'm using an NVidia GEForce II.


Don't know if this makes any sense, but if you'd like further clarification, let me know!

Thanks for such a fantastic library!

Lemur: By default GapiDraw will store all surfaces in video memory when running in full screen mode.. If you operate on these surfaces using operations that are not HW accelerated it will be much slower than if the surfaces were stored in system memory.. I'll add lots of HW documentation to the web site in time for the 1.10 release.

*Update* You can improve performance of video surfaces by calling "LockVideoSurface()" on the surface, then do all your un-accelerated stuff. When you are finished, just call "UnlockVideoSurface()".
