Tunable applyMipBias? #87

Open Aurora-Lex opened 2 years ago

Hi!

Im wondering if you have any plans for tunable applyMipBias, if that is even technically possible?

Reason being that while applyMipBias works great with conservative renderScale values, texture shimmering becomes gradually more noticable the harder you push renderScale. In my opinion the actual FSR and NIS scaling algorithms looks pretty good even down to renderScale 0.5, but at that setting texture shimmering is so eyestraining that I end up disabling applyMipBias alltogether.

It would be really useful with say, a 0.0 - 1.0 multiplier where, 0.0 MipBias is fully based on pre-scaling/internal resolution (Effectivly MipBias off) 1.0 MipBias is fully based on post-scaling/target resolution

That way you could look for a sweetspot and not having to disable applyMipBias completely.

Thank you for this great piece of software!

You can actually do this yourself in Nvidia Inspector; just disable in VRperfkit first.
