I'm using X-Plane on MAC OS High Sierra on a MacBook pro 2017 that support external GPU's (Graphic Processing Unit) that embeds Radeon RX570. Model is Sonnet eGFX Breakaway Puck Radeon RX570. it's supported by both Mac OS and Windows 10 actually
I use it with a few video/image processing software that already support it, some games do as well.
I can see that X-Plane doesn't recognise eGPU's connected to laptop at the moment. Any plans to support it ? That would be great as it would allow to use X-Plane with much better performance, good graphics and no lag on compliant laptops and personally my MacBook pro while I travel... ?
To look into this further, we will need to see a copy of the log from this test. Please send a bug report here.
"The expectation is that users with an eGPU will have it plugged into a second monitor. "
Why would that be a logical expectation? Only if you have a desktop like an iMac in which case you probably wouldn't bother with an eGPU.
If you have a MacBook Pro you will use an eGPU as your main monitor in all cases. So yes this does need fixing. And it does work in Windows bootcamp!???
A year on and still not fixed :(! This is poor from X-plane and the Laminar team. Come on guys, this is not a feature request per se. This is about getting the software to recognise and utilise all the available hardware at the OS' disposal, or letting Xplane pass onto the OS the such handling of graphics in the same way as Final Cut X or Adobe Premier can. My RX580 will soon become obsolete/outdated, if it isn't already, before a fix is made :s
No, that is not quite true.
It will work (almost), but you get frame rates that are a fraction of what you get with the on board GPU. It is un-useable. So don't bother at present. But this is known to developers and is the bug mentioned above.
If the latest beta has fixed this as ptrebian suggests then we'll all be happy.
But it does work perfectly in Bootcamp. I have x-plane running with my MacBook pro 2017 and eGPU in windows Bootcamp. Though the issue here was getting the eGPU to work in Bootcamp which can be a bit tricky depending on your Mac, firmware etc. I had to install the non-official bootcamp video drivers to make it work.
But I just wish the developers would fix X-plane then I wouldn't have to boot to windows to fly.
