With dx11 i have around -30 -40 fps once sunlight is in the sight With dx9 this drop is lower, only -5 maybe -10 fps. Also as you can see on first video i have fps 25-100. But once i had around +30 fps with same settings, fps counter was turned on allways. UPDATE Once i hit "create thread" button i found we have another new build Well, have not time to try all this again with new build, maybe tomorrow. i5 4670 MSI R9 380 8 GB DDR3 Radeon driver 14.5.1 Settings No AA, no PP, no agressive threading, all rest are maxed except no shadow second video. https://i.paste.pics/1OPTL.png https://i.paste.pics/1OPU3.png
