Low FPS with Sapphire Radeon Nitro+ RX 580 8 GB on late 2013 MacBook Pro 13" (Thunderbolt 3 > 2 adapter)
- Processor: 2,4 GHz Intel Core i5
- RAM: 8 GB 1600 MHz DDR3
- Integrated graphics: Intel Iris 1536 MB
The late 2013 MacBook Pro does not have Thunderbolt 3 inputs, so I'm doing the setup through the Apple Thunderbolt 3 > Thunderbolt 2 adapter.
I used the purge-wrangler.sh in order to make the computer recognize the eGPU. The card is now recognized by the computer and I'm running my 2K Asus monitor with HDMI from the eGPU. I tried playing Civilization VI in 1080p with pretty high settings and ran the built-in benchmark in the game. I got low results, it was mostly 15 FPS and 30 FPS at max. At the moment I don't have the exact settings that I used, but it wasn't running everything on max. I disabled shadows and some other stuff. I can give you the exact settings if that's necessary.
What I'm asking you is: is this expected given my setup? Are there some ways that I could optimize the eGPU and make it run better than what I got? Do you think it will run better with Windows 10 and if so, could you point me to some instructions on how the Bootcamp setup should be made?
Pending: Add my system information and expected eGPU configuration to my signature to give context to my posts
@tobias_gerhardsson can you run the Unigine Valley and Heaven benchmarks? I previously had the Aorus Gaming Box 580 paired with my 2014 Mac mini, so the setup is pretty similar to yours. I had benchmarks in 10.14.2 and Win10 which you can see here as a reference. This might help to troubleshoot if there is something wrong with your setup or if that's just the performance you get from the RX 580.
@tobias_gerhardsson I know that this may be a stupid question, but have you checked "prefer external GPU" checkbox in application info?
My setup is MBP 15" 2015, i7 2,2GHz and 16Gb of 1600MHz RAM + same eGPU enclosure and GPU as you have.
On Windows on internal screen I can run Witcher 3 on 1920x1200px uber settings without hair works @30FPS. It may be that your system is not capable to run Civ VI smoothly [email protected], given that 13" MBP may have crippled PCI line.
