You sure that guy wasn't playing on a potato? (Or a brand new Nvidia 5060Ti 8GB?) Low VRAM makes a lot of games look like crap, because it's either dropping textures or running like ass when you overflow VRAM.
A lot of people really can't communicate, or just aren't sure what they want in the first place.
So they can't explain over the phone either, but fifteen minutes of vague rambling lets them feel like they explained it, and there's no written record of what they did or didn't say so they can blame you if you can't work it out. It's win/win, as in they win and blame you regardless of what you do.
The problem with getting rid of everyone who tells you things you don't want to hear is that bad things still happen to you but now they always come as a surprise.
Last I heard about Mac gaming, games had to support Apple's proprietary Metal graphics API, so a game can't run on anything else.
Apple are trying to throw their weight around and forcing developers to go Mac exclusive like they do with iThings, but Mac users are such a tiny segment nobody bothers.
It was life changing when I realised uBlock Origin can block whatever I want from web pages and not just ads.
All the links at the right of an article, headers and menus that want to continue occupying screen space after I've scrolled down, the entire comments section on some pages. Bam, gone.
Pages with cookie banners that don't have a one-click reject all button? Just block the banner.
Instead of running a magnetic tape over the cassette player's sensor, you put an electromagnet on it powered by the headphone jack. The cassette player just reads the magnetic field and doesn't know any difference.
Fake resolution has it's place, the problem is when Nvidia pressures reviewers to put its cards running a fake resolution against other cards running native resolution on benchmark charts.
I can imagine showing someone the image and saying, "See the evil one in the middle? No, not that one, front middle."
