Because they no longer update that version. Here is the official article https://customersupport.frontier.co.uk/hc/en-us/articles/4405958019858-Elite-Dangerous-is-no-longer-playable-on-Mac

I've already made a bug report with the same report as this post at FB16809761 I can't include a small Xcode project because I'm using GPTk to try and test out some games already available in the wild. It seems like for whatever reason, when using GPTk. Once it allocates some VRAM, it never releases it. Unlike when testing out the game with DXVK+MoltenVK where it does free up the VRAM when it's no longer being used. Edit: I added some test videos showing the issue
