Please describe your issue in as much detail as possible:

Ever since Call to Arms update there is a performance drop (FPS, lag) that is caused by someone on B site of map Overpass walking in water. I do not even have to be near the site or see anyone walking when FPS drops. i tested being in connector, looking at wall. FPS dropped from 90-100 down to 20-25. then i made another test being in fountain area and FPS dropped form 90-100 down to 60-75.

Steps for reproducing this issue:

1. someone walks in water area on B site
2. FPS drops

this was not present before. with new telemetry it confirmed my suspicion that someone walking in water seems to be causing it. if i go to water my self there is a very small FPS drop looking directly at water and drop is also not on all areas. could this be sound related?

i have not yet noticed this issue in Anubis water.

Same problem. Any player walks in, FPS drops from 120 to 20. You can even use it to know if someone is in the water. Worst is Ancient and Overpass. It seems to happen in any map with water. Except Anubis. I think it might be because the water is clear. Dark water might be causing it.

Another thing. Every time I start the game it starts full screen windowed. I have it set to full screen. I have to go to settings, video and change the setting to anything else, put it back to full screen and enter. Every time.

Shoots is also effected, Ancient is particularly bad at the beginning of rounds, when your whole team (if playing as a T) is running through the water.

I have dropped as low as 10-20 fps down from 300.

Shoots becomes unplayable, as the issue with water tanking performance is mixed with https://github.com/ValveSoftware/csgo-osx-linux/issues/3350

I also notice this bug to a severe degree when we all start running at round start as T side on de_ancient. When we all take off the splash effects from the four members of my team takes my fps from hitting its 300 cap to heavy stuttering and skipping, effectively <10FPS while we get out of the starting water.

[gregor3000]

indeed - Ancient if affected as well. if CT goes though T and you are on another side of map or guarding bomb FPS will still drop. though not down to 15-20 FPS but it is still a drop down to 70 FPS (in my case).

interestingly Anubis does not see a substantial FPS drop when player are walking though watter. though there could still be some.

[ZeroYamaoka]

Its happens every on map where is water. Looks like water splash effect cause Vulkan render to lose performance

[gregor3000]

but you don't have to be near for the FPS drop to occur. so does it really have to do with rendering?

[NO-ob]

Yeah i have the same issue on ancient in t spawn, as soon as teammates start moving my fps drops from like 260 to about 40

[simifor]

I have performance with people walking through water (at least overpass and ancient). I tested on windows as well (dx11 backend) and that was also affected in my testing. GPU: RX6600 CPU: ryzen 5600G Drivers: Mesa 24.0.1

I tested practice mode in ancient before and while bots move

	FPS	GPU%	CPU%	GPU POWER
Linux (static)	160	99%	37%	100W
Linux (moving)	65	65%	42%	40W
Windows (static)	182	99%	48%	100W
Windows (moving)	82	59%	43%	63W

Numbers have some variance while testing, but this gives a rough idea about the performance loss. Vram usage was under 6GB on this 8GB card so it shouldn't be a significant factor.

[wildcard-f8]

I take back that it doesn't happen in Anubis. But it only seems to happen when a player walks in the small pool inside bombsite A, not outside.

[gregor3000]

Also on fountain in Inferno. Run around the fountain a bit and FPS in my case can drop to 25 from 120+. This did not happen before the update.

[n3m6]

Can vouch that this is happening in my case too.

I got a new gpu 6950xt and this issue is more noticeable because im playing on high graphics settings, on overpass my fps is about 330 when someone is in water on b short it drops to 260 and i can feel it instantly it so know when people are there it feels like im cheating lol

[oyvindln]

This is still extremely noticeable when playing on ar_shoots, whether it's a deathmatch with players or bots. I think some of the threading and performance fixes lately have reduced the impact slightly but it's still very bad.

[oyvindln]

Worth noting that this is not just a performance issue but also has the potential for cheating since it could give away other players position

[turrini]

This is still a big problem. Doesn't matter if Linux or Windows btw.

[gregor3000]

I tested with bots and another player. it is most noticeable now on overpass. bots or player in water means severe FPS drop in my case (down to 15 FPS) and it depends on the number that go through water. interestingly the water on bomb site does not cause as much drop if any. this is slightly better on Anubis, where drop is not consistent. but Ancient has a noticeable FPS drop as well when anyone goes through water on T side. this was also seen on Inferno (if people went through fountain) but i have not noticed it this week.
