Installed 4090 - Same FPS as previous 3080?

Mattsneaker · 26 Dec 2022 at 11:53

Hi all - i finally installed my 4090 this morning and excitedly loaded Forza Horizon 5 only to find the FPS is the same as when running on my previous 3080. Its almost as if some settings remain that limit the performance. I have reinstalled Nvidia drivers and turned of MSI afterburner profile (i think) as i undervolted my 3080.
Anyone else had this? Is there anything else i need to resintall?
I ran Speedway test in 3dmark and got 9823 points

when i swapped to 4090 from 3080 all my afterburner profiles were gone, only have 3dmark free so cant compare

What CPU are you running?

Have you tried running DDU (https://www.guru3d.com/files-details/display-driver-uninstaller-download.html) and reinstalling the latest NVIDIA drivers? You should not have to do this these days, however worth considering if you are having issues. Unless the game is CPU bound of course?

Ryzen 5800x and run in 4k so wouldnt expect a CPU bottleneck

The 5800X is still a strong CPU. I know some games like MS Flight Simulator are very much CPU bound until you start hitting 4K, even then, the CPU makes a big difference in that title. I'm not sure about Forza Horizon 5 though?

just ran speedway in 4k with 4090 at stock and my score was 6 582, so if yours is bad what is mine?

not sure if speedway ran in 4k actually - think 3dmark used a lower res. Will check again tomorrow

Do you have a frame limiter running?
Have you checked your card is boosting correctly?
Is your gpu being fully utilised when gaming?

I was expecting similar but get around 80 fps (same as with 3080).

What CPU do you run?

WizKiD · 26 Dec 2022 at 20:01

Hi, had this on a 4090 build I did on a gigabyte motherboard with a 7950X. Something in the bios was causing the 4090 to run slow. They released a bios update to fix it.

WizKiD · 26 Dec 2022 at 20:01

Ahhh sorry just saw you were on AM4 and not AM5.

Mattsneaker · 26 Dec 2022 at 20:03

I’m going to check for BIOS updates too - have a B550-f Motherboard

Doesn't Forza Horizon run at really high framerates? I bet you are bottlenecked even at 4K.

Not as much as I thought.

For Forza the benchmarks only showed a marginal improvement from the 5800x 3d over the 5800. Im sure i have some setting or drivers issues somewhere. Will investigate further tomorrow and report back

Whats monitor Hz? 4090 is 147 fps at 4K in Forza 5. 3080 is 75 fps.
