No matter if the server is full or not, COOP or AAS, Local or on the Internet, everytime I drop a smoke grenade or someone drop one close to me my FPS will go down to 15. It's worse in the first 10 seconds then it gets a bit better.

It was not happening in the last version.

Nothing was changed to smokes in 1.3.5, have you had the same issue in 1.3?

Are you speaking about handheld smoke nade, or UGL one?
Cause we didn't made any changes to smoke besides minima distance.

I can confirm!

This has been an issue in 1.3 as well. I always get framedrops when in thick smoke. For instance when I have to revive someone in the middle of a thick smoke screen, my frames drop to 10 or even underneath.




Dj.

Smoke is heavy on fill rate because it basically covers the screen multiple times with semitransparent particles, forcing a LOT of pixel writes. Some graphics cards just can't keep up.

If you're using supersampling (antialiasing mode where the whole screen is rendered at higher resolution), turn it off because that will make it much worse.

If you're experiencing fps drops when popping a smoke, it's time to overclock your dual-core processor or preferably upgrade your computer (anything from intel's 2nd gen cpu's) with a core faster than ~4ghz will run it like butter.

I disabled it even before reading your post and it helped a bit, thank you.

I upgraded my computer recently to a Core 2 Quad Q8300 but since PR runs single threaded and my CPU has a low clock (2.5GHz) it did not help much. I am waiting for the LGA1151 to become cheaper next year so I can do a decent upgrade.
