With any 387.* driver (387.22, 387.34) Talos Principle hangs during loading with my GeForce GTX 970 (occasionally it seems to load fine with 32bit binary, hard to find a pattern). Following error is always showing in dmesg afterwards:
NVRM: Xid (PCI:0000:01:00): 32, Channel ID 00000033 intr 00040000
going back to 384.* driver fixes issue.
