I expect this patch to be fixed by 1835e2f5baa376eab95c760951fcc6a3612aa6cd, on cards that support ARB_instanced_arrays. There were similar bugs that I expected to be fixed by this patch, and they weren't, so I kept all of them open for now.
I'll leave this bug open for a while and close it if nobody can confirm that it still occurs.
Unfortunately, I have rebuilt my machine since the original post and accordingly cannot be sure it works as expected under those specs. I don't see the same trouble on the new machine though. The performance isn't nearly as high as it should be with my significantly stronger machine, but I don't see the same dramatic fluctuation in FPS as reported. So, fixed? Maybe? RealGecko, can you confirm?
