Fps drop from 60 to 15 while looking thru scope and Firing many bulets at once
Assigned, NormalPublic


When i shoot looking through scope (mk200) fps drop from 60fps to 15fps, when particles are on very high,
when on normal then drop only little bit ,
and when i shoot without scope does not effect performance only when looking through scope! ,

this is weird because when looking through scope visibility area is a lot smaller than without.

i5 3750k @ 4,7 (i try on default too)

Steps To Reproduce

In options change to particles quality to very high and shoot at distance 500 meters with weapon mk200 with ARCO or RCO scope, 50 - 100 bullets at once (better go prone)

Additional Information

I need to put particles down otherwise game is unplayable even if i put other options down to normal and particles very high steel is the same issue.

So problem is in particles i think.

Try with different ATOC settings, set it to everything and set it to none, test both cases.
I noticed a similar FPS drop with ATOC grass enabled and looking through some grass in prone position with a scoped weapon.
ATOC disabled FPS did go up, lowering grass density even more (This is why we need separate grass density and grass draw distance settings!).

when i changed particles minimum like on the picture is fine, but i think is some issue with it , with my computer configuration should be fine even with particles on max.
