CoX doesn't respect chosen GPU

[Chance_Fletcher]

Hi folks,

I'll begin with my unique setup. Running Windows 11. I have two discrete GPU's for reasons. I have an AMD Radeon 6800xt and a 6600. I have an ultra-wide Samsung Odyssey G9 monitor that has a 240hz refresh rate. I use the 6800xt as the "Default high performace GPU", but connect the 6600 to the monitor. The goal is to use any resolution upscaling, frame generation or other adjacent-to-the-main-proccessing on the 6600, while freeing up the 6800xt. This has given me a significant FPS boost and has reduced input lag. This works 100% of the time, even for CoX, until very recently. It continues to work for all other applications or games I want to use it for.

 

My issue is that CoX no longer respects the chosen high performance GPU and will only run on the 6600. I don't believe there have been any game updates since July 8th, maybe there was a small hotfix I don't remember.

 

Things that I have tried:

• Add both the launcher and cityofheroes executables to the graphics settings and setting them to use the 6800xt
• Deleted and reinstalled CoX completely
• Checked the registry entries to ensure that the settings are being saved correctly
• Updated the BIOS to the latest version.
• Checked the BIOS to ensure I didn't mess with a setting; iGPU is disabled for instance and still is.
• Have reinstalled GPU drivers several times, using DDU to do a full wipe in safe mode. In fact, there was an update today and it didn't change anything.

 

I've kind of run out of ideas. The only thing I can think to do is to try a previous version of the GPU driver. My only problem doing that is that driver updates are almost necessary at this point as everything GPU is pretty much bleeding edge and needs constant updates to handle new games.

 

I currently have the game running on my Linux partition and it's working great on the 6800xt. But, Linux doesn't currently have the ability to split the GPU workload. It also doesn't support my monitor's 240hz refresh rate and so I can only get 120 fps out of it.

 

I know, it seems like a ridiculous thing to complain about, but I'm a PC enthusiast and tinkering nerd and when this kind of thing happens it tweaks my brain in a bad way lol

 

If any other information is required, please let me know.

Thanks for any help.

 

EDIT: I can see in the client.log file that it sees both GPU's and all their ports, but I don't see any way for me to force it to use the 6800xt.
