nope its adds latency or something I guess?

i doubt it's slower in 2D. i must have been more focussed on 2D when i was on the UD4.

almost sure it shouldnt be worse. but i struggled to match my ud4 times.
Probly just my noobness :)

it's not a guess...you know :) Chuch, look at it like a speed bump on the road between the cpu and the pcie slot, from where your 2D bench is being computed, to the display.

I'd be curious to see the same comparison in something more GPU demanding like Vantage or 3DM 11
