Thanks for the answer. Yes, my intention is to record the demo using normal settings, and next convert it to a video using the best possible settings. I didn't express my thought in a clear way.
But it's not clear to me which are the best settings.
I didn't know of r_ext_multisample, I'll try to understand what it does. But what about other settings?
Sorry, playing with r_picmip 9, I'm absolutely ignorant about SG graphics/settings.
