MSFS & AMD CPU

[iFlySimX 769]

Hello all!

Coming over from Intel to AMD, are there any setting in the BIOS I should turn ON or OFF that would help with performance?

All I did was enable EXPO/XMP. The 7800X3D's performance at stock BIOS settings seems to be more than adequate.

In my 5600 which is already old but performs GREAT I disabled the equivalent of hyperthreading, called SMT in AMD parlance..., in the BIOS.

Modern AMD CPU s are very good!!!

AMD -> PBO / Curve Optimizer

don't forget curve optimizer got mine set to negative 25 at the moment . free temp reduction , free increase in frequency , but your mileage may vary

As others mention you can use Curve Optimizer and gain a little more top end frequency and a little lower temp, and emphasis should be on 'little'.    Also, for sure disable AMD's version of HT, called SMT.  This amps up heat greatly and offers no better performance in my experience.

5800X3D here. And 4070 plain. The combined cost for both was under $900.

I used Curve Optimizer and ran long test on testing software. Improved with lower heat. But every few days a BSOD (maybe one every 100 hours). So I set it back to default normal and no more BSOD's for a year.

X3Ds are the best gaming cpus. Series 4000 are the best gpus. I have to turn graphic settings way way down when I don't run native FG which is what series 4000 can do.

AMD CPU boost (for 150-200Mhz dynamic overclock).

AMD SAM smart access memory on.

And you are good to go 🙂

I would double check about smart acces, maybe something wrong with my system, but on Kewr from Drzewiecki it gave my huge fps fluctuations.  not saying you should not use it but maybe in conjunction with FGEN, I don't know.....
