May seem like a pretty random question but, are there specific SFM launch settings that you use? Or do you mainly rely on Davinci Resolve to get extra details out of your works (if at all)? I believe you mentioned using that video editor before. If so, any tips on using that in terms of getting the best quality?
The only launch settings I use, outside of -sfm_resolution for 1080p and 2160p renders, are -nosteam -nop4. The former allows running Source Filmmaker without Steam Friends detecting it, and the latter disables SFM's built-in (useless) Perforce checks which cause save lagging when working with the particle editor.
