I have a really strange bug now: even on low settings the frame-rate is abysmal, unless I start sliding the brightness setting on the touch bar up or down, the frame rate then stabilises until I stop adjusting the brightness. It played fine on Sunday, so not sure what that's about.

My specs are:

MBP 2018 15"
2.9 GHz Intel Core i9
32 GB 2400 MHz DDR4
Radeon Pro Vega 20 4080 MB
Intel UHD Graphics 630 1536 MB
