Question FPS drops

[spt06]

Hello everyone,

I'm experiencing issues with FPS drops. Let me try to explain to you when and how it occurs. As a typical scenario - while playing CS2, my FPS drops from 400FPS to 200FPS (or even less, depending on the map), sometimes randomly, sometimes depending on the situation - smoke, grenades, etc. It's very frustrating. Let me give an example with League of Legends. Initially, it starts at 400FPS, gradually decreasing as the game progresses. This is natural, but then there comes a time when, for both shorter and longer periods, it drops to 60FPS, making the game unplayable. Similar occurrences have happened to me with Hogwarts Legacy - instatly FPS drops. I think it doesn't matter which game I play.

My components:
CPU: AMD Ryzen 9 5900X 12-Core Processor
Motherboard: ASUS ROG STRIX B550-F GAMING
GPU: NVIDIA GeForce RTX 4080
RAM: Kingston FURY 32 GB KIT DDR4 3600 MHz CL18
Cooler: ARCTIC Freezer 34 eSports DUO Red
Disk: Samsung 980 1 TB NVMe M.2
Power: EVGA 850 GQ

I've tried to resolve this issue in the following ways:

• Updated BIOS to the latest version (photo of BIOS version above)
• Uninstalled/Reinstalled the latest drivers for CPU and GPU
• Since that didn't help, I tried reinstalling Windows. (I formatted the disk - clean installation)
• Installed drivers

Unfortunately nothing has helped. Can I ask for your help on what else should i do?

CPU temperatures:

• Befor
• During stress test

Thank you very much for your responses and advice.

Monitor refresh rate make and model

I don't know if AMD's chipset drivers are supposed to help with this, but a problem with gaming and Ryzen 9s is that if there's any data sharing between cores, then the penalty if the data needs to go to the other chiplet is almost as bad as just accessing RAM.

So a common thing to do to prevent this from happening is to limit the game's affinity to one chiplet. Which in this case, you could try restricting the game to the first 12 threads (as this would be 6 cores on one chiplet, plus the SMT threads) and see if this helps.

Does that have anything to do with it?

I am having a very busy day so my answer is coming later. Thanks for the advice, I'll try it - for steam I can set it via properties - lunch options but what about games outside steam? I would like to try it everywhere but my knowledge in this sphere is absent. Could you give me a tutorial on how to set it up?

1. Launch the game
2. Open Task Manager
3. Go to the "Details" page
4. Right click on the game and select "Set Affinity"
5. Untick either CPU0-CPU11 or CPU12-CPU24

You could also try an app called Process Lasso. It'll effectively do the same thing, but you can automate the above for games you play often.

TBH, your cooler is a bit on the light side for 5900x. Stock temps would be fine, but it would be close to maxing it with PBO and or OC on the CPU. You need something stronger to let your CPU shine a bit more.

It's possible your CPU is throttling under load.

In the games make sure either vsync is on to match the refresh rate of your monitor. Also set game to 280 cap in settings otherwise it will just push the CPU to make frames that your not even going to see. E.g if game is posting 400 frames then the CPU is being hit harder then it needs too and it's just working overtime for zero benefit. This is probly why it's throttling back frames so drastically. This will also cause screen tearing in the game.

Only time you shouldn't have vsync on or frame limiter is if the game never gets close to the 280 refresh rate.

Keep in mind that a lot of games don't push the CPU close to its power limit, even at faster frame rates. I did some testing on my i5-14600K (rated for 125W) and even when games were pushing 400-500FPS, the worst it got was around 90W for Doom Eternal. I also tried Unreal Tournament 3 and Counter Strike 2, and they floated more around 70W. In addition, the lower power hungry games stick around 3-4 cores of activity at most.

So I don't think thermals are a problem per se. The CPU's not likely hitting its 142W PPT.

I've been silent for a couple of days now.
I bought watercooling to eliminate overheating and to perform the tests from the advice you gave me. Unfortunately, something happened, and my motherboard died. The motherboard lights up, indicating that it's receiving power, but when I start it, the power supply just clicks. When I remove the graphics card, RAM, and disks except for the NVMe drive, it still doesn't boot, just the power supply clicks. I suspect there might be a short circuit somewhere. Visually, the motherboard looks fine. Do you know what it could be? Alternatively, what would you recommend? Is it good to buy a new motherboard for this processor, or should I go for a new generation? If the latter, what would be the best combo for the processor? Just to add, I bought the NZXT Kraken 360 water cooling. Is that okay?

Once again, thank you in advance for the advice you'll provide.

when you installed the cooler did you remove the board ? double check around the board make sure all connections are in properly. double check behind the board that there are no random extra stand offs touching the board ( some cases add extra that arent needed.)

make sure aio isnt leaking near the pump or tubes. or radiator.

it wont boot without ram it needs

at least 1 stick in slot 2.

also reset cmos and remove battery.

if all that fails.

pull power cable out of wall make sure psu is turned off.

push power button and hold for 30 seconds if the pc springs to life for a second dont worry that is normal.
as what your doing is discharging the board of any power. then replug the cable back into power supply and wall and turn on pc.

if your using the adapter for 4080 ditch it there crap get a proper cable.

other thing to do if all fails is a psu tester

Thank you for your advice. I've discovered that when I reconnected the power supply to the motherboard, I made a big mistake by connecting it the wrong way round. I didn't realize it at all. According to what I've been told, this is precisely the mistake that "killed" the motherboard.

That's unfortunate hopefully the other component can be salvaged
