So it’s been a frustrating experience so far with the 9800X3D. I tried to troubleshoot some issues with it in this post thread:
Everyone was very helpful and I was able to increase my performance with a few tweaks, but when it came to VR, the situation went south fast. I was so disheartened that I did the last thing I wanted to do, put the 7800X3D back in. Before I took the 9800X3D out, I screen recorded 2 videos. One is a replay of a flight using VR, the other is a VR cockpit video where I tried to follow mostly the same path. After reinstalling the 7800X3D, I recorded the same videos expecting the same results. You’ll see in the videos that the 9800X3D produced
massive lag spikes compared to the 7800X3D, to the point of making it unplayable in VR (at one point the lag was so bad that I was thrown out of the cockpit). One video is posted below and I will upload the other shortly.

This post isn’t to complain, it’s to see if anyone here has experienced this issue and may have a solution. I’m not quite ready to give up on the 9800X3D, so asking anyone if they have any other solution that I haven’t thought of that might be able to explain why my performance is less than my 7800X3D.
