--- Comment #6 from Matias N. Goldberg <dark_sylinc at yahoo.com.ar> --- I'm back. I only tested texture and uniform buffers, not SSBOs. Results: * Setting UBOs to 4 byte alignments didn't seem to matter in any way. Performance didn't seem to be affected either. Nonetheless given that AMD always sets it to 256; this is what I'd recommend (i.e. there could be undocumented hw errors for edge cases?) * Setting TBOs to non-16 byte alignments breaks in a specific pattern (i.e. 4 byte alignments produce certain glitches, 8 byte alignments produce a different set of glitches, 12 byte alignments a different set, etc). Setting TBOs to 16 byte alignments fixes everything. I benchmarked 256-byte alignments vs 16-byte alignments-non-256-byte and couldn't see any performance difference (the sample kept around 46.50-47.00ms all the time). -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
