20:31 mannerov: siro__: Btw we still have mysteries to solve with the buffer locking flags
20:31 mannerov: Remember our tests ? hehe
20:31 mannerov: SYSTEMMEM is really weird
20:32 mannerov: Like it looks like NOOVERWRITE (which is widely used by apps) on AMD/INTEL does dirty all the buffer (not the locked region) BUT doesn't sync the worker thread (so the lock does affect draw calls from the past)
20:33 mannerov: at least that's what I deduce from the test results we had with our old tests
20:54 mannerov: Also the tests say that on INTEL if you write outside of the locked region for SYSTEMMEM, it isn't dirtied, but that's not true for NVIDIA/AMD
