New PC - Ryzen 9 7900X & Radeon 7900XT Massive Lag in most Games.

Wasn't sure exactly were to post this since I'm not 100% sure what the issue is as of yet. Some games run fine (Back4Blood 227 FPS) But on Star Citizen I'm only getting 5 frames even on lowest settings. And same issue on other games, terrible frames and lots of stuttering/input lag.  Only thing I really changed in BIOS was getting my RAM up to 5500MHz and enabling PBO which bumped my CPU from 4.7Ghz to 5.5Ghz. This is my first time building a PC and it's been a lot of learning as I go. Any help would be appreciated. 


Motherboard: MSI MAG B650 Tomahawk Wi-Fi ATX AM5

CPU: Ryzen 9 7900X 4.7Ghz 12 Core Processor

GPU: Power Color RX Radeon 7900XT 20Gb

Memory: TEAMGROUP T-Force Vulcan 64Gb (4x16) DDR5 5600Mhz 

Storage: 970 EVO Plus 2Tb NVME & Crucial Mx500 4Tb

Power Supply: Corsair RM850x 80+ Gold

Monitor: Gigabyte M27Q 27.0" 2560 x 1440 170 Hz Monitor (Using Display Cable and have tried HDMI to see if it changed anything)

Could be buggy AMD drivers but make sure in Windows Settings - Graphics you have all your games configured to run in "High Performance" which is your GPU Card.

If it is set at "Let Windows Decide" or "Power Savings" for any games change it to High Performance. See if that makes a difference.

Otherwise someone else that is involved in gaming will need to advice you.


I've tried this and it's still not working.
