Hmmm… good question, YourBoiCDX… it doesn’t really support an eGPU, so that’s out… you already have the Max RAM in there, so that’s out… apart from replacing the internal drive with an SSD ( after you backed up your stuff before, of course- you should do and use a regular backup on your Mac just to be safe and smart… the only downside for an SSD , it’s more expensive than a conventional hard drive, but it is way faster for accessing data , reading and writing data , 2TB would be around $250 usd plus installation… that might help somewhat… also get better virtualization software, eg CrossOver, Parallels or VMWare fusion ( which all cost more $) … really, if’n’ you’d Want to spend that kind of $ to do that you’d be better off getting a refurbished ps4 or Xbox one and playing Roblox and combat masters on that..
just my opinion though
