Unplayable. My PC can handle almost all shaders at native 1080p and 60FPS, the shaders i prefer are always High preset with Motion Blur and slightly configured to run at 1080p 60FPS anyway and still look great. (Just small things like DoF off and Shadow Quality or Shadow Distance increased)
You really should not use shaders with an Intel card, unless you wan't those effects so badly.
I would recommend you only low shaders if you want to hit atleast 30FPS on 720p or similar resolution. (Or just use Render Quality x0,7 which you already did.)
What specs you got? Is it same??
By the way, i got 30 fps if i use medium or high shaders (without DoF and Motion of course) on 720p. And I just want to test out not to play with Intel card, i know Intel card its really really not suitable to play heavy thing. I just mess around with it tho XD.
I usually play some games with my computer with i5 skylake + evga gtx 770 + 8 gigs of ram
Anyway thanks for reply and recommending me mate :), Cheers!
