[Linux] Frame rate drops when near / in the smoke

[CodeMonkey80s]

When near smoke or in the smoke the FPS drops drastically.

Any updates on this? I get that rendering smoke can be cpu intensive and stuff, but on my laptop im getting tenth of the fps in smoke which affects the gameplay quite a bit. If there is smoke stack near me in game, I literally have 2-3fps which is absurd. Kinda wish that csgo had the same option of cheap smoke as cs1.6 did, I dont even care that I see worse trough smoke (as opposed to pretty smoke) if it gives reasonable performance...

[alois-git]

I agree with the worst smoke option, been looking for that before posting here, I am actually back on 1.6 right now :P

[micb25]

I want to push this issue again. I did some benchmarks with fps_benchmark and recognized huge FPS drops. Framerate drops from above 200 to 25 FPS when entering the smoke (all settings set to low).

System specs

[vakkov]

Same happens with cs 1.6 when using the integrated intel card. The dedicated Nvidia with its proprietary drivers doesn't have that problem

[alois-git]

We are talking about CS:GO with proprietary drivers, I think cs 1.6 with open source driver and integrated intel card is a bit out of scope :D

[JFingerle]

This is still an issue - 450fps on average but drops to 50fps in smokes.

Edit: On win10 the exact same fps drops happen in smokes (tested with the "fps benchmark" workshop map). IMHO this issue should be renamed, it is not Linux specific.

[charbelnicolas]

Yep, still an issue, fps drop considerably around smokes. I'm on ArchLinux, latest kernel and latest nvidia drivers.

[henrym11106]

the smokes on that fps benchmark map are not representative of actual smoke performance, I suspect they are many smokes piled up. I actually got slightly better FPS in them on Linux last time I compared. they tend to max out GPU power cap though and that can be a limiting factor.

frame rate in smoke normally depends on a combination of resolution and GPU shader compute performance. in a normal smoke, FPS can actually increase. when standing near several smokes there tends to be a spike in GPU load and drop in FPS -on dust 2 I went from 500 fps to 280 when near 4 smokes just now.
