Replaced My GPU, But Now It's Lagging - Help!

Asked by TechieNerd123
I recently swapped out my old 3050 graphics card for a new 5060 Ti, and while the drivers installed without an issue, I'm experiencing significant lag. It freezes when I try to open the start menu, and any program I run also seems to stutter and lagโ€”it's like it occasionally catches up, but then lags again. The 5060 Ti is definitely functional; I pulled it from another machine after upgrading that one. When I put the 3050 back in, everything runs smoothly. Does anyone have suggestions on how to fix this issue?

It sounds like you could be dealing with a power supply issue. Double-check that your PSU is properly connected and adequate for the new GPU. I once forgot to plug in the power cable to a new GPU, and it performed terribly until I fixed it! Good luck!

You might want to completely clear the drivers for both the 3050 and 5060 Ti using DDU, then install the drivers for your 5060 Ti straight from NVIDIA. This should ensure there's no leftover baggage causing issues.

Make sure to keep an eye on your CPU usage when gaming. If itโ€™s maxed out, that could be causing your lag. You've got a decent i5-12400 with that card, but it's always good to check!

Try using DDU (Display Driver Uninstaller) to completely remove any old GPU drivers before reinstalling the new ones. This can often resolve conflicts that might cause lagging after an upgrade.

Have you checked the BIOS to confirm that your GPU is running at PCIe 4.0 speed? Sometimes the speeds can default to a lower setting, which could cause performance issues.
