Good day!
I recently bought a 2018 Mac Mini i5, bundled with an external AMD Radeon RX 560 graphics card (the eGPU device is a Sonnet eGFX Breakaway Puck). Using Mario Galaxy as a test game, the average framerate is about 40, which seems reasonable, but I get periodic bottlenecks, causing the sound to stutter and the framerate to dive, and I suspect the Thunderbolt interface may be at fault. Also, I made sure to set the audio to DSP Emulator Engine - DSP HLE emulation (fast).
Basically, I have two Thunderbolt hubs plugged into the Mini. The eGPU is the first hub and runs at full speed (40 MBps), and feeds my two monitors. The second hub is only Thunderbolt 1.0, has an optical audio-out feed that runs to my stereo. Does it seem possible that Thunderbolt bandwidth is causing my bottleneck, or is there something else obvious going on here?
Thanks for any feedback.
Sincerely,
Jabroni5
