Help with low FPS.

Hi All

I have a reasonable system and have recently upgraded my display card but when playing Mechabellum and in the later rounds my system is struggling and drops to 6fps or lower. I have checked my CPU, RAM and GPU utilisation with Task Manager and everything looks find, CPU at maybe 30%, Ram at 20% and GPU is not being stressed at all. Can you advise as to what the problem is? My PC spec is below:

Windows 10 fully up to date
Motherboard: Micro Star MS-C702
CPU: AMD Ryzen 5 3600 6 core @ 4.2GHz
RAM: 32GB (Can't remember manufacturer but it's good / fast)
GPU: Brand new Nvidia Gforce RTX 5070

All of my drivers are up to date.
I play Elite Dangerous and a few 1st person shooters which run fine.

Thanks in advance for any help :-)

ideally GPU need to be higher than cpu usage, what if you setting it 2K to 4k ultra,
you already update BIOS? i mean 3600 mean AM4 right

I have a question. To be clear is it specific areas of the game that always cause the same problem or is it the amount of time you've played that eventually leads to a slowdown in performance?

Like if you were to start the game up and load up that same area and begin playing where you last had the slowdown would it play fine and then eventually have a slowdown somewhere else or would that same area loaded up play slow form the beginning and the next area would play fine again?

post a cpuz validation link
http://www.cpuid.com/softwares/cpu-z.html
cpuz -> validate button -> submit button
it will open a browser, copy the url (address) and paste it here

Are you using the 5070? Maybe the new build is using the integrared GPU - ie the one in the CPU? It's a setting in BIOS.

Late game it has LOADS of ai and projectiles everywhere, it's your cpu likely getting bogged down along with your memory, as you cannot really have fast memory on a 3600.

Your motherboard is the MSI B450 TOMAHAWK MAX. Because it uses the B450 chipset it is restricting your new video card to only run at PCI-Express 3.0, significantly reducing the performance of the video card you installed. Although none of that really matters because the Ryzen 5 3600 is already a severe bottleneck for that video card due to it's performance anyway.

There's not really much you can do to improve performance other than upgrading your CPU/Motherboard/Ram to newer, faster hardware.

Ryzen processors without a G have no integrated graphics prior to socket AM5 (7000 series onwards), there is no other GPU for the system to use

CPU is bogging down performance and bottlenecking the 5070, even the 2080 Ti was capable of being too much for 3000 series to handle.

Looks like a problem with the game, maybe ask on the game forums?

System Requirements
Minimum:
Requires a 64-bit processor and operating system
OS *: Windows 8 and above (64 bits)
Processor: Intel, AMD 2 cores CPU at 2Ghz
Memory: 6 GB RAM
Graphics: AMD Radeon™ HD 7730, NVIDIA GeForce® GT 640
Storage: 10 GB available space

This can run on a toaster.

CPU and GPU are not a good match.....i have a 3080 and got rid of a 3700x to go to a 5700x and it was a massive difference in being able to max out my GPU.....

50 series has a massive driver overhead to keep up with on the CPU side....if you can find a 5700x for cheap or do anew motherboard with CPU and memory upgrade.....

by this logic, any cpu and gpu combo is bad

the gpu has 16 pci-e 5.0 lanes, but in the board its running at 3.0
which is not going to hurt it in any way

odds are something is set wrong or its using vsr and downscaling to the display res
or maybe bad cpu cooling causing throttling

who knows until we get more info from the op

with a strong gpu and weak cpu, older games will still run fine, never maxing the gpu, unless running at a very high res and display settings
people stretching the life of fx cpus did that, run gta5 at 30-40fps when capped by cpu, but maxed visual settings since the gpu was always capable of much higher

I have no experience with that game unfortunately, but that CPU is not strong enough for that GPU, and NVIDIA drivers have more CPU overhead than AMD. 6 FPS and lower though? That must be an issue elsewhere.

I have Ryzen 5 5600 with RX 9060 XT and I still run into a bottleneck in some games at 1440p.

Try to find cheap, used Ryzen 7 5700X3D / 5800X3D.
Or upgrade to Ryzen 5 7600(X)/9600(X) or even 7800X 3D or 9800X 3D, depending on your budget.

RTX 5070 has 16 PCI-E lanes, there won't be significant performance loss even at PCI-E 3.0.

Yes it will. This is reducing the video card's performance as much as -10% or more.

We know exactly what's wrong with their system: A classic system bottleneck is holding back the performance of their video card.

Reducing a PCI-Express 5.0 video card to PCIE 3.0 is as much as -10% performance or worse. No one should be using a 5.0 video card in an old 3.0 motherboard. That's just bad.

Not true, it's the CPU that's always the majority of the difference, not the bandwidth. If you have a fast CPU and just set the bandwidth lower yourself, you're barely going to notice with 16 lanes.

And that's with a 5090.
