Hey

Recently I upgraded from an 7900XTX to a Gigabyte 4090 and I feel like I'm struggling here...
I can't get good frames and I feel like I have something misconfigured...
I really don't know If it could be a RAM issue or If I should switch to a more beefy motherboard but I'm down to test any suggestions.
The reason I'm posting this is because I saw some benchmark videos of this GPU on "the finals" on 1440P low settings and its got over 300fps without frame generation.
video in question
I'm curious what am I doing wrong here.

Full specs:
  • AMD Ryzen 9 7950X with ARCTIC Liquid Freezer II 360
  • Gigabyte RTX 4090 WINDFORCE 24G
  • RAM Kingston 32GB KIT DDR5 6000MHz CL36
  • MSI MAG B650 TOMAHAWK WIFI
  • intel p660 ssd plus a few other HDDs and SSDs
I'll attach some footage of my "The Finals" Gameplay recorded with OBS and no it didn't cut performance I tested and I saw no difference in number while I wasn't recording.
I'm desperate for a fix because I spent a lot of money on this PC and its not doing what its supposed to do unfortunately.
 
after removing the AMD RX did you run DDU in Windows Safe Mode to remove all traces of drivers/graphical data and then install the latest Nvidia driver package?
you don't want any AMD driver or other data left behind.

and have you tried reinstalling the game?
game's stored compiled shader data can be different between AMD & Nvidia cards.

I did do all the above mentioned yes!

Could a fresh windows install work?
Is there any difference between Win11/win10?
(Im on win10)

I also have HPET disabled, GPU ACCEL disabled, XBOX GameBar disabled and Resize BAR and XMP enabled!

11 has quite a bit more built-in background nonsense running.
I've used it quite a few times and much prefer 10.
upgraded from an 7900XTX
was the AMD card running better?
or were you also struggling with performance with it?
don't know If it could be a RAM issue
verify that the kit is included in the motherboard QVL.
and that you have modules installed in DIMMs A_2 & B_2.

never trust YouTube videos for hardware performance.
always remember that these are posted to draw in views, most will state/do whatever they can to draw in a few more clicks and cannot be trusted as factual.

find a real GPU performance and/or comparison review or chart from a trusted source, like Tom's, to compare hardware.
 
When you're trying to push frame rates by lowering graphics settings the video card doesn't particularly matter a whole lot. The CPU determines the maximum frame date that can be possible. This article does a good job of explaining how the CPU can come into play (there's also a video version on Hardware Unboxed): https://www.techspot.com/article/2837-cpu-performance-4k-gaming/

I'm not familiar with the performance profile of The Finals but it's entirely possible your CPU and somewhat high latency memory are coming into play here.

Make and model PSU: wattage, age, condition (original to build, new, used, refurbished)? History of heavy gaming use - correct?

There are some built in Windows tools that can be used to observe system performance.

Task Manager, Resource Monitor, Performance Monitor.

There is another tool, Process Explorer, (Microsoft, free). However you may need to download the tool.

https://learn.microsoft.com/en-us/sysinternals/downloads/process-explorer

Try all four tools but only one tool at a time.

First run the tool after booting the system. Just open the tool window and watch.

Then once all is steady and stable leave the tool window open but drag the window to where you can watch.

Then work and/or game as usual while keeping an eye on the open tool window.

Watch for what changes when performance lags or you otherwise deem the system to be underperforming.

It will take a bit of trial and error to work out a method to work with any given tool and watch what is happening.
