http://bugs.winehq.org/show_bug.cgi?id=12557 --- Comment #57 from Roderick Colenbrander <thunderbird2k(a)gmx.net> 2008-05-04 09:54:13 --- The main limitation for older ddraw / d3d apps is the poor LockRect / UnlockRect performance. These calls on Windows give you direct access to e.g. the framebuffer (they can give you a direct pointer to the video memory). OpenGL doesn't provide this and we need to read the data from the framebuffer on a LockRect operation and need to write the result back to screen during an UnlockRect operation. On systems with PBOs performance is a lot better because they give you asynchronous reads / writes which results in that you don't have to wait before you can continue with other tasks. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
