Okay, I’m going to do a quick summary, because personally, when I’m looking for information, I do a lot of reading.
So, to summarize your RT 5700 XT will run the Reverb G2, with some settings revised downwards compared to a more powerful GPU.
BUT the problem here is the countless CTD crashes you might have with MSFS. Still among everything I have read, these CTD crashes can affect AMD 5000 and 6000 series GPUs.
If you’re lucky you don’t have CTD crashes it will be stuttering when looking down, but again if you’re lucky you won’t.
You can also have screens that turn black, with flashes.
Always the same, if you’re lucky …
To summarize, the HP Reberv G2 and MSFS is a lottery.
It can also depend on whether your PC is running on AMD or Intel.
