My FPS doubled under DX11. Doubled.

I saw your other post room, I'm excited for DX11 for this very reason. Both games can get abit hungry and I have a mid-high end computer so I should be able to run ultra all the time.

I have Ryzen 5 2600 6-core CPU, 8gb DDR4, R9 280 3gb, MSI m/b and driving stock SCS trucks with all gfx maxed and at 400% I get 100+ fps at the garage.
