Given the new 2019 Macbook Pros start having some "average" discrete GPUs, such as the Radeon 5300M, how can I know the best settings - under Catalina - for a specific game? (no bootcamp please)
When will the Radeon software be released for Catalina?
I'd like knowing the best settings for XCOM 2 WOTC, for instance, and I'd prefer having precise "best" settings rather than using "auto" or trying to change everything parameter by parameter...
Many thanks in advance
All drivers either for OSX or Bootcamp are released and supported by Apple, not AMD. You would likely be best to ask someone in a Mac forum.
There are not many users here with Macs and I do hope you get the answers you want. I use macs too and find these to be some good forums for mac users:
