PIX on Windows, @DirectX12 team @Microsoft

[Kostas Anagnostou @KostasAAA]

PIX timing capture functionality has been extracted into a separate library to offer recording of a large number of events including, among others, GPU top/end of pipe timestamps, object lifetime and memory residency/eviction in-game. https://t.co/XB0Av5Qt8h

[DirectX 12 @DirectX12]

PIX 2408.05 has been released! It adds custom texture/mesh visualizers support, faster playback, many shader debugging improvements, and a lot more:

[DirectX 12 @DirectX12]

PIX 2310.30 is now available!

Major perf improvements (particularly the "Pipeline" tab), fast+friendlier NVIDIA plugin, hit/miss shader debugging, TLAS hierarchy tree, DXR ray viewer... and much more.

Check it out here: https://t.co/HEQAKryLEC

@_plop_ Congratulations! 🥳

[AMD GPUOpen @GPUOpen]

Don't miss our primer on #Microsoft's just-announced GPU Work Graphs in @DirectX12 🔥

📈 Enable more direct methods of solving complex problems
📈 Reduce memory constraints
📈 Improve cache utilization
📈 Improve GPU thread saturation
📈 And more!

We’ve just released an exciting preview Agility SDK which introduces Work Graphs, a way to enable more GPU autonomy by allowing shaders to dynamically generate additional shader workloads! This release also includes Wave Matrix and accelerated AV1 Encoding https://t.co/iRd25aWGVL

Looks like D3D12 is going to let you allocate CPU-visible VRAM on systems that have ReBAR: https://t.co/RIBiNzhMhz

[DirectX 12 @DirectX12]

We have a new PIX on Windows release, with more support for DXR & new D3D runtime features, new IHV plugins, D3D residency events in Timing Captures, and a wide range of changes to make PIX more useful! https://t.co/GzUJ0o1eZ8

[DirectX 12 @DirectX12]

Today we released a downloadable preview version of WARP, with several major bugfixes and SM 6.7 support. For more, see here: https://t.co/sJfHkihiHv

@chriskwallis @nico_m__ @nadrin Hmm yeah! Looks like one of the graphs is at 100% for almost all of the event though, which graph is that?

[Austin Kinross @austinkinross]

@nico_m__ @chriskwallis @nadrin Interesting! PIX has a hw counter graph for this on NVIDIA, I would be curious if it’s complaining at you.

[Austin Kinross @austinkinross]

@m_ninepoints The joint state isn’t valid on a compute queue. So if you transition to the joint state on a graphics queue then technically you need to transition again before you can use the resource on a compute queue. More details: https://t.co/ipwV1nh5PX

@amjazzbre @rgbaxyzw @JanOrszulik Ah thanks for figuring that out. Agreed, that should just work. I suspect Live++ is spawning a lot of processes which is tripping up PIX. We’ll investigate. Feel free to contact us again if you have other issues/questions etc.

[Austin Kinross @austinkinross]

@amjazzbre @rgbaxyzw @JanOrszulik Did you figure this out? If not then please feel free to email [email protected] and we’ll help solve the issue. We like to think that we’re responsive/helpful. I’d start by clicking Home->Output in the PIX UI and sending the log to us.

[Chris Bieneman @thegreatbeanz]

I’m proposing adding HLSL support to Clang!

@JJcoolkl Congrats John!

[Adam Miles @adamjmiles]

Xbox ATG (Graphics Team) is hiring!

Remote working is a thing.
3 positions open, one each at SDE 1, SDE 2 and Senior.

If anyone wants to reach out to me and get a feeling for what we're all about, my DMs are open!

Updated PIX on Windows hardware counter documentation, including guidance for interpreting counters and counter acronym definitions on AMD, Intel and NVIDIA: https://t.co/O4d4il5kPc

[Austin Kinross @austinkinross]

@simon_coenen @createthematrix Hmm. Are you using SM6.6 bindless? That can slow down the pipeline view a lot pending some PIX changes. Otherwise the pipeline view shouldn’t have slowed down: if you can send the capture to [email protected] then we would happily investigate.

[Austin Kinross @austinkinross]

@createthematrix @simon_coenen Yeah PIX’s pipeline view shows accessed resources (not just bound), including resources accessed via ResourceDescriptorHeap etc. If it’s not working for you then please send the capture to [email protected] if possible, we’d be keen to investigate. https://t.co/ebw6zoMWuX
