This demos close to 150 images per second on a 4090. I can do faster but this should be good enough to prove the perf I can get.
Presuming you have ArtSpew installed:
pip3 install -r req-maxperf.txt
pip3 install -r req-sfast.txt
Use the following brings up the GUI. Use the step, go, and stop buttons until your eyes go bleed.
python3 maxperf.py <batchsize:max=10>
If a batch size of 10 causes an OOM reduce the number.
