GPA stream mode lack geometry info

Hi,

I try to use steam mode, but the result lack geometry info. Is this a bug?

zczh - I'm pretty sure it's because you are trying to play back on NVIDIA. Capturing on NVIDIA is fine. We work hard to try to make GPA work on all GPUs (no promises), but if you play back (meaning open the frame) on NVIDIA you won't see all the data because we don't code for NVIDIA architecture.

So, the capture collects the API calls, that's why it's usually okay to capture on any GPU. But you have to play back on an Intel GPU to get all the data. So if you are running on an Intel processor, there is almost always an integrated GPU. So after opening GPAs Graphics Frame Analyzer, but before opening the frame you want to analyze, in the top right LEFT corner of GFA, click on the name of the GPU. That will open a dropdown of the GPU options on your platform. Choose an Intel GPU. Even HD or UHD. The framerate and ms/us per op might look atrocious, but the analysis is almost identical. If you are using DXR without a discrete Intel GPU, you may not get full support - we are working on that - making GPA better with other platforms' DXR implementations.

Let me know if you have any other questions.
