Wine 3.3 PBA is A LOT better than the normal versions to play league on linux, without lutris runtime the game crash everytime on lubuntu 18.04 with wine stable installed to get out of the “dependency hell”
so i think the better script needs Wine 3.3 PBA and Lutris Runtime activated.
my hardware: INTEL Q9550 2.8 GHZ, GTX 750 2 GB, 7 GB DDR2
with NVIDIA DRIVER 396.24
wine PBA = 60 stable frames, min 46 (i only use with 60 frames cap)
normal staging versios= 30 frames or less
edit: wine ge-3.6 is better than the 3.3pba
