one of the largest yes, but the latter part of your statement is completely off.
just talking about nvidia AIBS alone off the top of my head, theres: MSI, Gigabyte, Asus, Zotac, Galax, Colorful, Inno3d, PNY, Gainward, Palit.
and this is just nvidias optioins. There’s a lot of competition. EVGA was a favorite to those living in the U.S due to having reletively better customer service, but it was far from not having competition.
The whole point of the conversation is that the other platforms arent doing any work for the consumer.
To this day, epic doesnt even launch on linux officially, and requires a 3rd party launcher to even play its games. Epics first party games are on the list of games that dont work on linux.
There’s clearly one company who puts more effort onto the consumer front than the other. Epic doesnt even need to make a custom OS like valve does, it just needs to get their own launcher working, and their own games working, which they dont and refuse to.
To say that Epic is doing better for the consumer is disingenuous (however it does better for the developer though)
