Describe what you expected should happen and what did happen. Please link any large pastes as a Github Gist.

Expectation: to play with the FPS I'm used to, varying between 100-160

Actual: it starts great, FPS stays in 100-160 range, but maybe 20 or so minutes in it starts getting noticeably worse, dropping to 40-60 and deteriorates down to 15-30. When it's got that far I usually either stop playing or restart the game if I'm in a matchmaking game.

Steps for reproducing this issue:

1. Boot up computer
2. Start game, joining either of deathmatch, casual or match making
3. Play for 15-30 minutes

I tried starting both steam and the game from the command line, but it didn't reveal much useful information, beside that some dylibs didn't properly load.

Ah, and another thing I probably ought to mention is that I noticed that Steam was using more, sometimes twice as much, than csgo, but maybe that's expected? The commands contained hints that the threads were two renderers and one gpu thread.

(Developer here btw, so I'm used to digging around in logs etc to sort things out, happy to provide further info if there's something useful I've missed)

[nyaray]

I just noticed that Steam is idling at 100-106% at the moment.

EDIT: this is after a matchmaking game where the issue described had occurred and I restarted Steam and the game once near mid-game.

EDIT2: forgot I had the game idling in the background in case I needed to run console commands for the issue. I'm going out to play in the sun now...

~Most likely the mac variant of #1206.~

[perryventas]

I have exactly the same issue since the last update. My system is a Retina iMac Late 2014, with a AMD Radeon R9 M295X 4096 MB. It is really unplayable after about 15 minutes. Restarting CS Go doesn't help, a reboot is needed to make it playable again for a short time frame (although I didn't test if restarting Steam alone would help)

Here is my system information: https://gist.github.com/coin3d/60782bd96a9fa747115bd547223f8543

[nyaray]

@kisak-valve in that case, do you have anything you'd like me to do in order to (dis)prove that hypotheses?

I was thinking I'd start out by:

• quitting chrome (and other known resource hoggers)
• using screen mirroring with my external monitor, to not create more unnecessary pixels
• lowering settings and screen resolution

[kisak-valve]

The strongest indicator would be PCIe bandwidth utilization, but I don't know if that's exposed in any meaningful way on Mac.

[nyaray]

Oh, ok.

To begin with, I reinstalled Steam and CSGO and started playing on minimum settings. It went just fine. Then I started chrome, the biggest resource hog I was running alongside of CSGO and didn't have the issue. Lastly I turned off screen mirroring and it worked as well.

@kisak-valve yeah, unfortunately I couldn't find much info on how to monitor, supervise the PCIe utilisation :/. I'll fill in with more info if I get the issue again and manage to notice/figure something out.

Maybe it is the same for me or another issue entirely. Have gotten af new MacBook Pro 15" with TouchBar 2.8ghz Kaby Lake i7 and RadeonPro 460. It struggle to get more than 80fps anywhere in the game. Only caveat being i run High Sierra, which have Metal2

[nyaray]

My performance has improved vastly and I'm now running on a decent resolution to boot. Don't really know what changed. :/

EDIT: I'm also running chrome, some other things and have two external monitors connected, one of which I'm using to play the game on. Computers/software ¯\_(ツ)_/¯

[ghost]

Lagging too. Every time I look at someone I goes down to 30fps

[lamka02sk]

I can confirm this is also Linux problem. I didn't play CS:GO for a long time on Linux, but when I tried to play, it is literally unplayable. Really bad performance after few minutes. I don't exatly have steady 30 fps, but my fps is jumping from 0 to 280 all the time. So annoying. Also the RAM usage is abnormal = 2x of Windows usage.

Wake up Valve!

[ghost]

The bug is still here... when shooting it goes down to 20fps. Valve we need a bloody fix...

[wheedlingBanana]

Confirm that this issue persists. I would like to add that activity monitor indicates that Steam uses up to 200% cpu (I have 4 cores) and the percentage of CPU used by "system processes" increases to 50-60%

[MrPasty]

Can confirm I have been having this issue for a while now, really frustrating as frame rate drops from 160+ down to around 24 and is unplayable. I seem to get this happen everytime i play and often when the map switches to office! Steam please fix this

[lamka02sk]

As we see Valve really don't care about people playing their games. I already stopped, because it's unplayable and I really wish other people would stop playing too. The most broken game in the world.

[kiroma]

I don't think that blatantly writing that Valve doesn't care about their players is right. Don't forget that Valve didn't even make any CS. It's all been work of a small team, that has partnered up with Valve. Also, CS:GO is not the only CS game out there. I played CS 1.6, CS:CZ, CS:S and all of those work perfectly fine. Also, Valve makes other games like Dota 2, which runs amazingly well on Linux, compared to any other cross-platform title. That being said, CS:GO is the only game that runs so terribly bad on Linux/MacOS, though that also does apply in part to Windows build as well.

tl;dr: Only CS:GO runs bad, other Valve games run well.

Any new info on this issue? I have been trying to play some comp these past few weeks but needed to restart steam every 6 rounds is really inconvenient XD.

[pavel-odintsov]

I hit same issue. After latest upgrade (one-two weeks ago) my FPS dropped from 80FPS to 14FPS. It makes playing the game impossible.

I have MacBook Pro (Retina, 15-inch, Early 2013) with Intel HD 4000 1024 MB.

[wheedlingBanana]

After the new macOS update, i no longer have this issue :)

[pavel-odintsov]

Could not confirm it. I have 15 FPS. Previous version could do 80 FPS. Right now it's impossible to play. Again. It happened 5th or 7th time for last 3 years. I really disappointed.

[wesblake]

I think my issue is the same, do we have a fix? It's gotten worse and now I can't play for more than a couple minutes. I'm on Ubuntu, 17.10 at this point but had this issue for multiple versions. Other games (via steam) run just fine so I know it's just CS GO issue. So basically.... A year or 2 ago this didn't happen, things were fine. After a game update (sorry don't recall exact one) this happened. During game play, sometimes right away after joining, sometimes seconds, sometimes many minutes, my FPS would drop from well over 100 to 2-4 fps, so bad I can barely exit the game. Over time with game and/or card updates it seemed to get better (more time in game). I then had just over a month without my computer so I haven't played until yesterday. Now it's worse, I can't get more than a couple minutes every time and I'm done. Oh, and same as above, restarting the game or the steam client doesn't help. I have to reboot the machine. I3, 8GB Ram, Ubuntu 17.10, GTX 750 with latest "proprietary tested" via additional drivers, v384.90. I also tried using the official graphics-drivers ppa to get the latest drivers but that didn't help so I'm back to tested. Thanks!

[kisak-valve]

Potentially related for nvidia linux users with nvidia's 378.xx-387.xx driver: https://devtalk.nvidia.com/default/topic/1026874/

[wesblake]

I suppose I could do that, I've tried newer drivers but not older. Without fiddling too much I can try 340 series as they are part of the additional drivers options. If something changes I will comment back.

UPDATE: Well this is interesting, and shows me it's an Nvidia issue and that they are pushing for performance over stability. I'm on 340.104 now and while the issue remains, all aspects including performance are degraded.

• FPS used to float around 170-180fps with newer drivers, now it's 110-120
• The issue itself occurs much less often now.
• When the issue occurs, the drop is to around 30-35fps now instead of 2-4fps I'm sticking with 340 I guess until Nvidia figures their stuff out, I can live with 100-110 if I can actually play!

[pavel-odintsov]

Works for me now :)

[kisak-valve]

Can the other Mac users retest this issue? If it's still happening, please copy your system information from steam (Steam -> Help -> System Information) and put it in a gist, then include a link to the gist in this issue report.

[wesblake]

Still not an Nvidia issue, just different on different Nvidia driver versions. I forget this does not ever happen on at least 5 other games via Steam on the same machine, so it's still an issue with the way that CS or it's engine uses Nvidia on Linux/Unix

An issue with very low FPS come back again :/

CS:GO is broken again for Mac. It happened 4th or 5th time per last two years. Really, I have no idea how developers managed to do it again.

But I pretty sure that my CS/GO on my MacBook Pro (Retina, 15-inch, Early 2013, NVIDIA GeForce GT 650M + Intel HD Graphics 4000) is impossible to play because of 15 FPS.

It's so sad.

[eServerus]

I have the same issue. FPS decreases over time from the moment the game starts from around 80-107 FPS to 15-25 FPS.

With in-game steam FPS measuring I noticed continously decreasing frame rate while I was in lobby with active game window (watching the game while it was in idle). After 5 min it drops to around 70 FPS then after another 5 min drops to 55 FPS, then to 45 FPS and so on down to around 15-25 FPS. And that's just in lobby. Frame rate persists and it continues to decrease also during match.

I play with lowest graphic settings possible with double buffering. At the beggining it is fine but over time it is not playable anymore and I have to restart the notebook in the middle of the competitive match to be able to play normaly again. (It is not possible reconnect in time without loosing a couple of rounds.)

Symptoms are simple, frame rate decreases to unplayable minimum over time. It must be someting accumulative like memory leaking or something.

Here is my system info: gist

[ahcbsa]

Same issue here. Can't get over 50 FPS and sometimes when playing Casual games, it drops to 15-20 FPS.
