Tramadol Prescription Online A few days ago I stumbled upon a strange behavior of the drawIndirect function and I’ m curious to know if it only happens only on my PC or if it’s a more generalized issue.

Currently in my engine I have a lot of objects drawn with drawInstanced(). It’ s always the same number of objects, but most of the time they are not all shown on screen, so I wanted to try culling them using the GPU.

The idea is simple, a compute shader will do the culling and build two buffers, one with the objects that are on screen, and the other with the parameters for a drawIndirect function.

Usually I prefer to progress step by step, so I started with a compute shader that only write the drawIndirect buffer, with the constant number of objects, and send that to the DrawInstancedIndirect() function.

https://giannifava.org/2ddllky I wasn’ t able to find anoter AMD card to test, so maybe it’ s just something wrong on my PC. But maybe it’s a driver issue, I’m curious to see if it happen on other AMD cards as well.
