Fixed texture initialization on low-memory Macs with the Metal graphics backend.

Works great now, thank you so much

I pulled some past `config.ini`s from my computer backup to check.

Prior to 2.0.45, it looks like I had mostly the same settings except "native resolution" was turned off as I couldn't get good performance on my 4k monitor.
