I don’t actually spend much time tinkering with parameters. I usually just load up the base preset for whichever shader I deem the “right tool for the job” at the moment. Usually, the older the system, the grungier I like it
However, I did take a little time this morning to play around with crt-royale settings to try and reproduce the look of my NEC XM29+, which uses a slotmask and is a little less sterile than my PVMs (which crt-aperture already captures well, IMO), let alone one of the high-line-count PVM/BVMs that kurozumi’s preset is based on.
It looks okay at 1080p but looks a lot better/closer at 4K:
If anyone wants to try it, just take the kurozumi preset and replace the parameters down at the bottom with this batch:
