Maybe it's time for game developers like Epic to support Linux and make gamers choose Linux as their desktop
In the current market, this assumes a few things that simply don't work. Platform adoption drives game software development on the PC side of things. Though some of us do, most people do not purchase a high-end PC exclusively for games. They purchase it to do something they need and might add a high-end graphics adapter to allow them to play games. This often means buying a Windows box. If a game developer released a great game exclusive to Linux, that game would be played by very few people (and would be screwed by all of those graphics issues you mention). It's possible if Steam OS and Valve's platform gains wide adoption that game developers will focus more on Linux, though.
The economics of game development seem positively scary to me as a software developer. For major titles, they throw millions of dollars into development in hopes that a game, costing around $50 (and widely pirated) will generate revenue for about a year. And the success of a game is largely determined by factors that are risky, similar to other visual art-forms. Maybe the topic isn't one anyone cares about? That money is flushed down the toilet. Contrasting that with business software which can cost well over $50 and have a lifetime of several years, it doesn't surprise me that game companies look to subscription MMORPGs, paid DLC to existing content and in-game (effectively "paid-for cheats") to make money. Getting them to be willing to spend more to support a one-off platform with existing difficulties supporting high-end graphics scenarios is unlikely. Consider that a business case for an expensive piece of software like Adobe's Creative Cloud could be made far more easily. The software even has native support for Mac OS and Windows, yet they are unwilling to support Linux. That makes me a lot less hopeful we'll ever see great games running in Ubuntu without Wine.
