oh man, embarrassing it is
Unseating really helped. by securing the card by the screws, GPU got lifted out of the seat a tiny bit.
see here, bus load very low, fps on standard high and 1920x1080,±70fps, butter smooth
Good to see that early access games can help troubleshooting system. I mean i play a lot, all the new actual games, and never had a problem,always high fps, thats why i was wondering.
Many thanks for all your help and tips.
