degasus 3d5e0a6d3d move ogl-only settings into backend 2013-03-25 15:14:24 +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 c7d75ee437 GLSL: explicitly check for gl errors for pinned memory 2013-03-16 10:08:46 +01:00
degasus 2c9c4d0f01 remove syncing on hacked buffer 
nvidia does wait for their gpu on syncing, so removing it.
But now, we have to recheck it on every plattform

degasus 5534d7e8c3 Revert "remove flag GL_SYNC_FLUSH_COMMANDS_BIT on syncing" 
This reverts commit 025f8d342f.
OSX may wait forever, so fix osx freeze

degasus a650ae8c7b workaround for base vertex. damn old nvidia driver 2013-02-26 23:15:55 +01:00
degasus 025f8d342f remove flag GL_SYNC_FLUSH_COMMANDS_BIT on syncing 2013-02-26 21:48:35 +01:00
degasus 9332775b68 default upload method for nvidia is buffersubdata 2013-02-21 21:59:40 +01:00
degasus 40e17b4cb8 add option for hacked upload and disable it by default 2013-02-21 18:18:44 +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 376a807dea first try of osx fix, mostly by pauldachz 2013-02-07 10:34:29 +01:00
degasus e7a8d3f854 check for GL_ARB_sync, it's in ogl 3.2 2013-02-06 01:05:19 +01:00
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 :-)
