Hi,
Is anyone playing the game with the latest iMac and 5700 XT graphics card? What kind of performance are you getting? So far, I am using the default Bootcamp drivers but is there any boost to performance of using the PC drivers (I think need to install some unsupported hacks). I get about 18 fps in Ultra at 2K. How does this compare to standard PCs?
Thanks!
Running FS in Windows on Apple hardware is basically just limited by the AMD GPU (and perhaps some other stuff but significantly less so). I have an AMD 5700XT so I can boot windows and OSX on my system and it simply can’t keep up with nVidia hardware at any settings really. I fly only in the A320, run a mix of med-high in windowed mode around 1500px high for a widescreen like view on a 4k display and I get anywhere from 15-45 fps or so depending on time of day, location (city/rural), altitude (ground/FL320) etc. I find this is acceptable visually for the IFR flying I would like to be able do in the sim, but which is currently limited in functionality. If you’re flying around in the Robin, you’ll get way better frame-rates and probably have way more fun.
Thank you - Do you use bootcampdriver from bootcampdrivers.com? Thinking if that adds any performance boost …
I have a 5700XT and a Ryzen 5 3600 on an X570 motherboard with 32GB of 3200 RAM. Of course, it’s a Windows machine.
Wholly disagree that the 5700XT can’t keep up: I get as high as 70 fps, and never below 40 fps even at busy “hand-crafted” airports.
I think the problem is running software designed for Windows on Boot Camp.
For the record, I am typing this on a MacBook! 
I don’t see how I’m going out on any sort of limb saying a 5700XT can’t keep up. I mean, passmark puts it on par with a 2060 super and below a 1080ti even, which is generations old now. I’m not saying there’s something wrong with it, but it’s absolutely not as fast, and it’s the current AMD top of the line offering and it’s unquestionably the limiting factor on any system running a 10900. Of course that’s about to change but will Apple support the new card right away (if a real person can even buy one)… who knows.
@GuyJean2000 I have a hackintosh and boot Windows and OSX via the Clover bootloader.
No argument that the Nvidia GPUs benchmark quite a bit better than the best Radeon card.
My point is that a hardware suite designed for the Apple OS will not be as efficient as native PC hardware. The OP asks about using drivers other than the Bootcamp drivers: that seems a logical place to start.
I built a Hackintosh many years ago using native PC hardware and firmware designed to emulate the UFI environment. It ran OSX software just fine, but never as well as the iMac I used at work.
Using an iMac to run a demanding bit of native Windows software is a stretch; I would guess it will never run as well as it would on a PC.
Just my $0.02
I’m running Windows on an external SSD on an iMac 2019 i9 32GB and Radeon 575X. Resolution is 1440p (half the monitor dimensions in both directions) and practically everything at “high”. The sim runs smoothly and without any hicks so far. Performance even increased, especially after the Xbox-Update. With these settings, I can even fly alongside the skyline of Manhattan or take-off from London City with a reasonable framerate. No complaints. But, as mentioned afore, the GPU is also here the weakest link in the chain…
