I tried LSU [1] with wine-proton on the KDE Plasma desktop with RTX 2070 SUPER recently and had only a limited success. Baldur's Gate 3 and W40k Spa= re Marine 2 failed to load with errors spamming similar to [2]: err:virtual:try_map_free_area mmap() error Cannot allocate memory, range 0x7f600000-0x7f650000, unix_prot 0x3. I tried both ZFS and UFS and had ~20 GiB of RAM spare. Neither worked.
