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.	2013-02-19 15:51:48 +01:00
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	2013-02-19 13:18:48 +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 :-)	2013-02-05 00:53:14 +01:00
degasus	2a1f592d82	first try for pinned memory, complete untested	2013-02-01 17:04:27 +01:00
degasus	3bf4ffe7fa	usable sync of ringbuffer	2013-02-01 16:43:08 +01:00
degasus	3af9840a4c	stream by map and sync ... but not working perfectly, so disabled	2013-02-01 15:15:25 +01:00
degasus	878bd7f26c	implement streaming by bufferSubData, split upload and allocation in ringbuffer	2013-02-01 12:30:08 +01:00
degasus	30170575c8	create StreamBuffer class for ogl upload	2013-01-31 23:11:53 +01:00
