RTX 3080 underpreforming

[12345scott]

Hello everyone,

I am new to this forum so if I should look elsewhere for this information let me know!

The issue that I am having is that my 3080 FE is severely underperforming in most games. I have looked over just about every forum related to the topic and got very little help. I have done a number of things I have found in them as well as in Youtube videos and the problem is still persisting. The main game that I am trying to fix at the moment is Fortnite. I am running at 1440p (DLSS Performance) Epic for all settings (I have turned this to low for all and there was less than a 10 fps gain). I have RTX off and with all that I am getting 70-130 fps and it's jumping wildly between them. My GPU usage never tops about 30% and my CPU stays around 80%. I know for sure that something is up because my buddy has an Acer Predator Helios 300 with a 9th gen i7 and a 2060 and an external 1440p 144hz monitor and it getting consistently over 144hz. If you have any suggestions for me I would be so grateful.

Some of the things I have done include:

- Updating my bios

- Updating my Graphics drivers

- Setting windows to performance mode in multiple different places

- Turned on windows game mode

- Turning off G-Sync

- Turning off Nvidia Reflex

- Turning off all but my main monitor

- Downloaded afterburner and checked my temps which sit in the mid 70s

- Undervolted my card

- Downloaded GPU-Z and made sure I was using PCIE x16 gen 3

- Turned on low latency mode in Nvidia control panel

- and probably some more that I have forgotten about

 

My hardware is:
MSI Tomahawk b450 max
