* Adds a preference that disables intensive rendering on different multiz layers (#71218) ## About The Pull Request It's kinda hacky, but it is nearly the same as just rendering one z layer. We allow people to ENTIRELY REMOVE most plane masters from their screen. This has the side effect of disabling most visual effects (AO is a big one) which saves a LOT of gpu. We rely on planes being essentially layers to ensure things render in the proper order. (outside of some hackyness required to make parallax work) I've kept parallax and lighting enabled, so visuals will still look better then multiz pre plane cube. It does also mean that things like FOV don't work, but honestly they didn't work PRE plane cube, and FOV's implementation makes me mad so I have a hard time caring. Reduces gpu usage on my machine on tram from 47% to 32%, just above the 27% I get on meta. I'm happy with this. Oh also turns out the parallaxing had almost no cost. Need to remove it as a side effect of what I'm doing but if I could keep it I would. There's still room for in between performance options, like disabling things like AO on lower z layers, but I didn't expect it to make a huge impact, so I left things as is Also fixes a bug with paper bins not respecting z layer. It came up in testing and annoyed me ## Why It's Good For The Game Ensures we can make multiz maps without running into client performance issues, allows users to customize performance and visual quality. ## Changelog 🆑 add: Adds a new rendering option to the gameplay preferences. You can now limit the rendering intensity of multiz levels. This will make things look a bit worse, but run a LOT better. Try it out if your machine chokes on icebox or somethin. /🆑 Co-authored-by: Mothblocks <35135081+Mothblocks@ users.noreply.github.com> * Adds a preference that disables intensive rendering on different multiz layers Co-authored-by: LemonInTheDark <58055496+LemonInTheDark@users.noreply.github.com> Co-authored-by: Mothblocks <35135081+Mothblocks@ users.noreply.github.com>
