SOLVED: Disable the Integrated Graphics in Device Manager and RDR2 will work again. God knows why.

Red Dead Redemption 2 through Rockstar Launcher

Hello everyone! This is my first post so I hope you can bear with me if I'm posting this in the wrong forum or anything, and sorry for the really long post, there's a TLDR at the bottom. Btw, love this community!

First a short background to my current situay: After days and days of trial and error I finally got my eGPU setup working with Win10 in Bootcamp sometime late last year. Simply booting Windows with my eGPU plugged in sort of worked - the GPU was detected and fully functioning - but I was stuck with the flickering Windows logo on my internal screen. I finally realized I could get AMD Xconnect to work and thus enabling both displays by booting my Mac holding the option key while the eGPU was plugged in, then when the screen where I could select which OS to boot came up, I unplugged the eGPU, waited about four seconds, then hotplugged it again exactly at the same time as I selected the Windows partition. Tadaaa!

This has since worked perfect for me, and still does really, except suddenly out of nowhere, Red Dead Redemption 2 wouldn't start. I'd been playing it flawlessly for a couple of months and really love the game, so this annoyed me a lot. The game just won't boot, no error or anything. After pressing the "Play" button in the Rockstar Launcher, it changes to "Loading", followed by "Exiting" and then back to "Play". I've tried every single solution I've found online, including AMD driver wipe and reinstallation, nothing works.

After days and days of trial and error again, I realized that if I booted Windows like I did first - with the eGPU plugged in from the start thus leaving the Windows logo flickering on my internal screen - RDR2 started up fine. No idea why. It just works. But there I am, stuck with the god awful Windows logo just waiting to burn into my internal display (as happened once but thankfully went away after a few days). I can also start up RDR2 if I switch graphics setting to the built in Intel chip, but that obviously just won't do.

Has anyone experienced a similar situation and did you manage to find a solution? All other games and apps work fine, GTA V included (although that's through Steam). Any help would be greatly appreciated.

TLDR: Although it worked before, RDR2 now won't start when eGPU is selected. It works when internal screen is disabled (with annoying flickering Windows logo stuck on it). Also works when built in Intel chip is selected instead, with horrible performance.

@nebbiolo, I would recommend using an EFI boot loader so that you can keep the iGPU activated when cold-plugging the eGPU. For Apple T2 Security Chip Macs, the modified apple_set_os v0.5 works best.

@itsage, thanks for your reply! I’ve tried using the EFI as described, but with no luck unfortunately. I do the left-right-left dance, but still it’s just error 12. The loader also seems to cancel out my previous solution (hotplugging synced with booting windows from the partition startup screen), because now that won’t work either. Could my version of windows (see top of original post) be the issue?

SOLVED: For anyone who may have this same issue and wind up seeing this post through googling the problem, after litterally months of trial and error I found a solution.

Simply disable the integrated graphics through Device Manager and you are set! RDR2 will run fine again. I do make a habbit of enabling the iGPU again after I'm done playing before shutting down Windows, just in case having it disabled would mess up my already extremely fragile eGPU Boot Camp gaming setup.

This helped for me! Thank you man! Lifesaver!

 

What graphics settings u have in RDR2, as i keep getting pushed out of the game after about 20min in, maybe drop my graphics settings a bit.

 

Thanks again!

@jens_engels, I'm not sure exactly what settings I have, but fairly high on most settings and 4K resolution. I'm one of those people who prefer things looking good and running at ~30fps rather than lowering settings and playing at 60 or 144fps. In other words: I'm old, haha. I've never been kicked out of the game though, I think, so that sounds a bit odd.
