By sheer coincidence I have just been Googling render thread earlier today to find out what it actually means. There’s surprisingly little on it, especially as it relates to MSFS. The best I can gather is that it is akin to a complete CPU package of work that has been finished by the CPU and is now waiting for the GPU to execute.
Or I’m completely wrong and in need of a good smack. I honestly don’t know.
What I do see is that my CPU times can be say 7ms, my Rdr thread at 19 or even more ms and my GPU at 27 ms and I’m GPU bound, but if the Rdr thread goes higher than the GPU count I’m Rdr thread bound???
But again, from what I understand, if the RDR thread turns from yellow to red that means that it is the bottleneck… or is it still the GPU that has fallen behind in carrying out that chunk of work?
If someone could explain what the heck it really is, I would be most grateful. Also how to interpret the Dev mode counter properly.
Edit: I have sometimes come across REALLY high Rdr thread numbers with some third party aircraft that makes the sim unflyable. The freeware H135 helicopter is a prime example, which starts out OK, but then the timing gets longer and longer so that the Rdr thread is so high I get 5fps. Yet the far more complex H145 payware chopper has way lower and consistent Rdr thread times and works fine with good fps. It’s really confusing.
