Water Cooled Bucket List PC build for flight sim

My first few attempts to fly in MSFS 2024 on this new PC were disheartening. In spite of the really fast new hardware. All I had was stutters and CTDs - which all come down to graphics settings.

There are a lot of good tips on this forum, but not always easy to put them together. After a few weeks of learning, I’ve finally enjoyed a few flights stutter free. I was missing 3 things, which allowed the sim to run smoothly for me:

  • My Samsung TV originally showed up at 60Hz in Windows, which I thought was fine. The TV is supposed to be VRR capable (not G-Sync, however), and I thought that was automatic. It turns out, I had to set it to 120 Hz to unlock VRR.
  • I enabled GSync and Vertical Sync in the NVIDIA Control Panel, which I think allows MSFS to then control VSync. Not sure if this had an impact.
  • Maybe most important, the tip in another thread to set MSFS Max Frame Rate to 30 and then use Frame Generation to double back to 60 not only worked - it allowed me to increase the TLOD to 400 and LOD to 200 (the max). This makes all the difference, found in this thread:

A quiet test flight across New Zealand in the C172 at 60 fps, with max TLOD and Ultra settings, and the rig stayed very cool. After 8 months of putting this together, a small victory! (It stops the x2 Frame Gen when you put MSFS in the background, which is why it only shows 30 fps):
