Guys, how is the latest driver 18.4.1 faring compared to 18.3.4 using SRBminer?

I didn't realise the major Windows update would flatten the display drivers (f***ing Microsoft). I now have the choice between putting my previous driver on or use the latest.

Any experiences to share?

EDIT: oh well, what the hell, went with the new driver and... no big change in hashrate.
