using a default geo and render OPs, if I append an ssao TOP (default settings, except it uses full ssao resolution), my performance drops to 30 fps on a gtx 460m. Is such a big performance hit expected on a 460m? i don’t currently have access to another machine for comparison, so maybe that hardware is just not powerful enough. But I expected a 460m to deliver a bit more performance, so maybe something is “wrong/slow” with your SSAO implementation on a 460m (just a thought, as in the previous build it didn’t work at all …)?
thx
