RTX 4090 not utilizing full potential

Not open for further replies.
I uploaded an unlisted yt video showing it in 5120x1440 with the settings selected (DLSS on). I had GeForce experience showing fps in the corner but for some reason it doesn't show it in the video, so i wrote what it was showing. It also shows GPU usage. It went above 30% barely, but only because I was screen recording as well. I also tried it at 1920x1080 (not shown in video) and the fps went up to 120ish and jumped around a bit. DLSS on as well.

 
To add to what has already been said:

Games need to be properly optimized, sometimes they just aren't and the end consumer suffers.

Your GPU will not be running at 100% all the time, and it's good that it doesn't, that could theoretically shorten the life of the card, as with any other components.

Speccy would not pull your ram specs, try hitting CTRL + SHIFT + ESC, click more details, Performance, and then take a screenshot of the memory tab for us, it would be useful if you knew the memory model or advertised speed as well.


This is my laundry list, it's a good starting point for troubleshooting and should get you an idea what's going on:


1. Try running the following programs, also try to keep at least 25-30% of your disks as free space.

Run Disk Cleanup (check all the boxes) this will delete things such as your recycling bin, so make sure you don't have any files you want to keep.

Run Defragment and Optimize Drives, run this on your drives.


2. Disable any overclocking or changes to power/performance settings

Undo any overclocking you may have done (if any)

Settings > System > Power and sleep > Additional power settings
Make sure your power plan is set to balanced, anything else could tamper with the wrong settings and cause issues.


3. Check for Operating System Corruption

Right click on the Windows logo in the bottom left and select Windows Powershell (Admin)
Run these three commands separately:

sfc /scannow

Dism /Online /Cleanup-Image /CheckHealth

Dism /Online /Cleanup-Image /RestoreHealth

These will take a while to run, do not close out of Powershell while they are running, if one fails then move onto the next and then loop back around.

Note: It doesn't hurt to make a system backup before you make all these changes, save any important files of folders. While these changes shouldn't cause any issues, better to be safe than sorry.


4. Unplug unnecessary devices.

If you have a gamepad, extra monitor, external hard drive/flash drive, or anything that is not essential to using the computer plugged in, unplug it.


Once you have completed all of these tasks, restart it (using the restart option in the power menu) and re-test.



DDU:



Run DDU and download a fresh installer executable from here.

An important note: You MUST download the driver executable and disconnect your computer from the internet before running DDU, otherwise Windows will automatically download drivers (which you don't want).

Once you have ran DDU in safe mode, boot up into a normal Windows session (ensuring that you aren't connected to the internet for even a moment) and run the NVIDIA installer.

Restart your computer from the power menu and see if this helps.
