raytracing

I’ve been playing a bit of Minecraft this weekend and noticed much worse raytracing performance than previously. After a bit of investigation it looks like a regression was introduced with 1.16.220 which has substantially reduced performance, dropping from around 90+fps to 30ish, this is on an RTX 3080 with DLSS turned on at 3440x1440. After a bit of troubleshooting it looks like its related to v-sync, changing: gfx_vsync:1 to gfx_vsync:0...

One of the main reasons for getting a GeForce RTX 3080 last year was for Minecraft, so I can play with raytraced/RTX lighting enabled. I was expecting to take a substantial hit in draw distance - with RTX disabled I’d always play with at least a 64 chunk draw distance. Disappointingly the maximum view distance in Minecraft with raytracing enabled is only 24 chunks, at least as far as setting it in the user interface....
