Bad 3090 performance in CS2

[MiszS]

I tested my pc with a 3090 and my friend's pc with a 6950xt with the exact same CPU and ram specs (7500f). In the same spot in CS2 (long doors on dust 2) I get around 430 FPS in all max 1080p, meanwhile the 6950xt easily gets 500 FPS in 1440p. Ik that it is slightly faster, but the difference is definitely not that big. My other friend also gets the same FPS in game with his 5600 + 6900xt combo, with the 6900xt being only used 60%. I thought that the 3090 might be fake because I bought it used, but it has to be real because it definitely has the entire 24GB of VRAM, as I loaded AI models that take up almost all of it, it has a 3090 PCB because if the NVlink connector, and it performs pretty good in other games. Even if someone were to go out of their way to solder a 3080 core onto the 3090 PCB, it still shouldn't be getting that much less FPS

Specs, temps? Not all PCs are same, everyone PBO enabled, undervolting, cooling, etc.?

Asus tuf 3090, stayed under 60 degrees during that test, undervolted to 850Mv 1860MHz, PBO enabled. The 6900xt does often get getter rasterization performance though

[starsmine]

its hard to draw conclusions bassed off a single game, espeically when you are at 430 fps so any latency changes between systems will have a more apparent effect.

Try testing other games.

 

because the difference between 430 fps and 500 fps is essentially non existent

Thats also 1080p vs 1440p. That's not the only example, as i mentioned my friend consistently gets around the same FPS, while on a weaker CPU, with his GPU only being used 60%

and hotspot temps?

 

what is your exact RAM you got, and you friend's RAM? if they know

[toasty99]

This is normal. Counter strike has such insane fps numbers you're gonna see massive differences between different hardware. 

You don't have a fake 3090, that's too much work for anyone to do. It is real. 

 

I suspect your memory is why your fps is lower anyways. Counter strike likes fast memory with tight timings and obviously you need to have two sticks to get dual channel. 

 

If your 3090 isn't overheating under load, then don't worry about it you're good. Enjoy the 430 fps, it's enough.

Have you tried not undervolting the GPU? That's likely the reason. Heres some numbers for comparison:

74 degrees max after some time gaming, I just turned on my PC an launched CS, so the hotspot temps are like 55 degrees, but the FPS is still under 500 with the GPU being 100% utilised.

Both PCs have literally identical RAM, so idk how could that be a problem, we both have 32GB 6000MHz CL30

Gives maybe 20 extra FPS

[MiszS]

I actually just retested both PCs, and the 6950xt only gets like 50 fps more which is about what I'd expect, but on my 3090 I get terrible 1% lows of about 15ms per frame, instead of almost none on the 6950xt PC. The only difference is that I overclocked my CPU, but shouldn't it decrease the 1% lows instead of increasing them?

[toasty99]

I just think you need to enjoy the game and stop looking at meaningless fps numbers. I think it's ram, 6000CL30 tells me nothing about the sub timings and how the motherboard is running the ram. Regardless though, you got 400 fps and it doesn't really matter. 

 

Play a real demanding game like Cyberpunk and if you still have issues then be concerned. Counter strike is such a light game that even a tiny difference leads to wide fps swings, and you should largely just ignore the fps in it.

Counter strike is a game with such shitty 1% lows, that I can't enjoy it. 500FPS was on a map with no bots, so I can accurately test the difference. On the new maps I literally get around 180FPS with even lower 1% lows, which just looks like shit, and is nowhere near 360Hz that my monitor has

What's identical RAM? Do you both have same G.Skill/Teamgroup/Crucial/Corsair/Silicon Power/ADATA/Kingston brand and same model?

 

What SSD do your friends have CS and OS on?

 

CS2 is a CPU bound game, so if your friend has "better" 7500F it's possible it's just a 7500F that clocks higher than yours even if you both have PBO enabled

Not the same RAM brand, but if just the brand makes a difference this big with ram the same spec, that is just bullshit. I have a lexar NM790, they have the NM710, why would that even matter? We both have windows 11. As I said, I get GPU bottlenecked not CPU very often, but the 7500f doesn't even clock higher on the other PC, it stays around 5GHz

[AI_Must_Di3]

RTX 3090 is a tough card to deal with and its mostly because its a top tier unit WITH half its ram on the back of the PCB directly in line with the other 12GB of ram on the front side. Depending on the placement, the brand, the cooler, and whether its had the custom cooling work done, and done correctly, its going to run hot and do weird things. Of course, the other guys here have absolutely valid points about the comparisons, cpu bound gaming, whether youre using Geforce experience...which will hose everything and the rest of your build is going to add to the issues.

  I own it, have fixed a few others and im sure this is going to be a unpopular opinion, but its the truth.

It's not bullshit at all, faster parts can simply get more fps sometimes, because they're just faster.

 

And trust me, you do get CPU bottlenecked, (or bound)

 

CS2 will never run 100% on CPU, because it won't use all 6 cores or 12 threads, even with the new engine the game is too simple.

 

is this the RAM you have?:

do you know your friend's RAM?

 

 

What have you tried to resolve these issues? Did you try any setting changes? You probably tried driver updates right?

 

Did you update chipset drivers when you built your PC?

I built both of those PCs, and the friend has some Gskill RAM, don't remember which now, and that is the ram I have, just in white. I tried changing the settings in Nvidia control panel, like 10 different undervolts with overclock and without them too. I just recently installed the new driver for my GPU, so this can't be a problem, and I did install all the needed drivers for my mobo, wifi etc. I am 100% sure that it's GPU bottlenecked, because it can get like 400 FPS in some places on 1 map, but then gets under 200 FPS on the new map, with the GPU usage being 100%

As I said the card is the asus tuf and runs perfectly fine, the hotspot is under 75C and the memory temps stay under 90C

GPU is 100% because you have unlimited fps,

 

have you tried changing any Windows settings?

 

or few bios settings?

Well yeah, because of unlimited FPS, and because the GPU is too weak, I don't see your point. If I limit the FPS to 360 it doesn't change anything

I added CS2 to the graphics settings on windows, and set it to max performance. The only performance settings in bios that I changed is PBO with 5.3GHz overclock, and enabled EXPO

[AI_Must_Di3]

Ok, well that actually tells me theres more of a cooling problem than you think, cause the hot spot and ram temps shouldnt be more than 10 C apart, so the back ram is cooking and feeding the extra heat through the rest of the pcb, which means it wont last long at those temps. Of course, the temps only increase and get worse from here. Dont do the cooling mod if your not good at modding, overclocking and tinkering and def dont do the copper plate or try to use liquid metal or youll ruin the card. Copper slabs fitted to the ram with very little TIM paste is the way to fix it so it stops thermal throttling/cooking itself and you can at least try to pull more out of it properly. Theyre not fun cards to own.

under 90 degrees on memory is after gaming for a while, they don't "get worse from there", I don't see how that is a problem, as all 3090s have hot memory

I mean as it ages, dust buildup, component use/aging, etc... its only going to get hotter and more headaches. Its not going to get cooler..... unless you mod it, correctly.

Well yeah, but the temps aren't a problem right now, so why would it even matter? I have a problem with bad FPS right now, not in the future

Idk why you keep calling RTX 3090 "too weak", that's like calling Lamborghini "too slow"
