degasus 53377425d1 OGL: enable buffersubdata in detection 2013-03-28 12:18:39 +01:00
Ryan Houdek ff61dc3840 Switch to using bitfields in the streambuffer class so we can exclude buggy streambuffer types. This disables pinned memory on ATI for GL_ELEMENT_ARRAY_BUFFER because it seems to be buggy. This fixes ATI for me. 2013-03-23 15:37:01 -05:00
degasus efcfc5c014 workaround for GLEW_AMD_pinned_memory and older glew versions 2013-03-04 12:40:23 +01:00
degasus 50f4bf114e Revert "map_orphan_and_risk - next try for upload method"
This reverts commit 17747fcfb8.

On orphaning, some gl drivers do heurisitics where to store the buffer.
As the hack may only work on pinned memory, it would be much less deteministic.

degasus 17747fcfb8 map_orphan_and_risk - next try for upload method
should work around nvidia600 driver issue which will flush gpu on syncing
also increase buffer size by orphaning

degasus 1d86dafbe2 evil hack: map the buffer once and use this pointer after unmaping
This isn't allowed by gl and may _only_ work, if the driver uses cpu bound buffer.
But it may speed up :-)
