I see zero improvement in stability with this update. Before and after this update I cannot use dlls or dlls frame generation .dll file versions 3.10.6. If I do, then CTD every single flight.

So I use 3.10.1 and never ever any CTDs at all. This has been true for SU Beta 5 1.7.28, 5 1.7.30, and 5 1.7.32.

So I just choose the 3.10.1 dll files in DLSS Swapper and all is perfect.

In the release version SU4 performance is worse than the beta and there are occasionally small stutters. Which I never get at all in the beta. So I love this beta.

Hi,

I'm using the 5.1 betas and haven't had any issues switching the DLSS and DLSS FG DLLs to 3.10.6 (preset K) and FSR 3.1 to v3.1.4 via DLSS Swapper.
I'm using a 9800X3D, 32 GB RAM with a 4070 Ti Super, multiple screens (main FS screen is 4k) and lots of hardware add-ons.

Predominantly I'm flying the Fenix A320 with 3rd party airports.
SU5 (prior to 5.1 beta) I was getting worse performance compared to SU4, but performance in 5.1 has slowly improved back to near what I had in SU4.

No problem with DLSS Swapper with this 1.7.34 Beta. v310.6 applied.

Check my free MSFS sceneries : https://flightsim.to/profile/vbazillio/trending and my hardware configuration.

Probably "stability fix" placebo or pre assumption, but this build actually performs better than the last one. Just completed a short flight to Surabaya with F-28-3000, BATC, GSX, FSLTL, and Rex Core. Or maybe because of the server load, not as packed as weekends.

Why 3.10.1 and not 3.10.4 which is the last version I use with my 3090? 3.10.5 and 3.10.6 provide no additional benefits for me with the 3090 but the 3.10.4 is rock solid.
