Hi all, I've recently been working on adding indirect draw calls (using Unity version 2020.3.25f1) with our app. I've noticed some unexpected results from render stage traces in RenderDoc for Oculus and I'm wondering if anyone has insight into this. ...

That would be great! How should I send you a capture? (The forum doesn't seem to let me upload .rdc files). I've taken another RenderDoc capture that demonstrates the issue. This capture isn't from our app, but I've created a simple test project usin...

An update on this - I've done an additional test and am still getting an issue where indirect drawing with OpenGL seems to take far more CPU time than expected. When I add an extra direct draw call (glDrawArrays) into our app, the CPU time taken for ...

Interesting - that's good to know re splitting render passes when there's too many draw calls. In this case the number of draw calls seems okay though. Just took another RenderDoc capture and was 16 draw calls per eye, so 32 draw calls total in one f...

Thanks for that! I've done a low overhead trace. Interestingly the gap still appears in this one, and also the same result with one surface appearing both before and after the gap.

Thanks for the insight - that's interesting re the performance differences on Vulkan. Are those differences on OpenGL too? I'd be keen to hear more about what type of performance differences you're observing with direct vs indirect draw calls, if tha...
