I’ve been trying (and failing) to optimize a project that seems to have an overhead of ~8ms both in CPU and GPU time no matter what I do, while doing A/B editing on a secondary instance of the editor I noticed that if I loaded the exact same project, the secondary instance performs as expected. This behavior can be replicated using a Notch Block in TouchDesigner too. At first I thought it was a TD bug but the same behavior appears in Notch Builder (issue report @ TD forums). FXPlayerHost exhibits no such issue with a single running block.
NVIDIA RTX 4090, driver v528.49
Windows 10 22H2
How to replicate
Load the shared project file in 2 Builder instances, see them perform differently.
Being a new user I can’t attach the project file here, however, I have made it (temporarily) available here: test.dfx - Google Drive
