discussion More dx12 info on maxwell...not supporting as stated

[Bond007]

The whole barrage of dx12 feature levels and supported capabilities on varying GPU is seemingly never ending, with various sites expressing which they consider will be more important.

Supposedly nvidia's maxwell doesn't support (at a hardware level) some of what was thought. What's your take on it all?

ASYNC Compute isn't required for DX12_1 feature level support. I don't know what the issue is? They never claimed to fully support it.

AMD does support it through their compute engines though.....

Yeah, the whole thing is a little mysterious to me too. Another tempest in a teapot perhaps? There have always been games that ran better or different on the competing brand cards. Why is this any different? The stuff about NVIDIA trying to persuade them to leave stuff out is suspicious but who knows how that really went down. Nice feather in the cap for AMD though so good for them!

It really doesn't mean anything to me until such time as we see PC games that take advantage of DX12. With ports being the norm these days... I'm not even sure I expect to see too many of those that I'd want to play.

Ark: Survival Evolved will be rolling out a DX12 patch, but it looks like it was delayed.

Yeah I have read that somewhere, a programmer for the game developer said that in Maxwell there is only one graphics compute engine while GCN architecture has 8! That is why Nvidia was falling on it's face in the benchmark. DX12 will be a boon for AMD's APUs dealing away with their handicap in IPC and doing more in the multithreaded arena. Apparently the Nvidia driver was presenting a hardware feature that apparently was just software emulation.

This is the issue I guess only time will answer. Since nothing currently has every feature that dx12 contains, which ones will end up being most commonly used and most beneficial to the gaming experience (both visual quality and fps). It could cause some interesting benchmark issues in different games as they roll out.

Maybe pascal will be delayed till nvidia gets a comprehensive features list so it can check off most if not all features. But those gcn cores is amds wild card it seems.

Someone should tell AMD Marketing that, since they have been saying it for months now.

IMO, AMD just cried "Uncle" with that, and I suspect that something is about to drop where AMD is going to get spanked by nVidia. If I had my guess, it would be one or more of the features that nVidia has that is in feature set 12_1 that AMD doesn't have. If I was a betting man, it would be Rasterizer Ordered Views.
