Re: [Mesa-dev] [PATCH] nv50, nvc0: disable depth offsets when there is no depth buffer

I'm pretty sure it's undefined in GL (because there's no defined minimum resolvable difference in depth buffer format), IIRC this is stated somewhere but can't remember. d3d10 has a definition which doesn't make much sense (as it still says to use the unorm formula in this case for which "r is the

Wait a sec. Nevermind. It's something else. Trace replays fine in Mesa 13.0.3. Ignore this patch. On Sun, Jan 15, 2017 at 4:08 PM, Ilia Mirkin wrote: > Well, the trace in question rendered just fine on NVIDIA blob... I'm > kind of assuming that I just missed something in

Well, the trace in question rendered just fine on NVIDIA blob... I'm kind of assuming that I just missed something in the spec, or all other HW works this way, or ... . On Sun, Jan 15, 2017 at 4:06 PM, Axel Davy wrote: > Shouldn't this be fixed in wine, rather than in the

Re: [Mesa-dev] [PATCH] nv50, nvc0: disable depth offsets when there is no depth buffer

Shouldn't this be fixed in wine, rather than in the driver ? Yours, Axel On 15/01/2017 21:57, Ilia Mirkin wrote: While I can find no support for this in the GL spec, this is apparently what D3D9 wants. Also appears to fix a very long-standing bug in Tomb Raider: Underworld and Deus Ex: Human
