I think I am lucky in that, while I dont have the very latest Graphics, I do have an utterly ridiculous number of PCs, and they all have some form of O/S or another, be they Windows, Linux and a couple of Hackintoshes, plus one real one just for when I need to legally grab a new image of the latest POS version of MacOS.
But I have an utterly ridiculously large collection of Steam Games, and, I also have Steam installed on Windows, Linux, and Mac, and on the Linux and Windows Laptops too.
More recently I knocked up a SteamOS PC for a giggle ( almost a waste of time to be honest, but there you go )
Now, this has allowed me to play a fair number of games, in al lformats, plus I have tried a few games under WINE and they have all had varying levels of success / failure, but I have to be honest, and for the most part, Windows has always been that one step ahead... ( Sometimes miles ahead too ), however, I do have a few games that have been AWOL from my steam list, and for those, I have had to install them under Wine. I have also been using PLAYONLINX as I have found that to be VERY reliable in getting many things running that can be awkward. I can name a fair few games that dont like wine/PoL but this is not an issue for me most of the time. I just accept they dont like it and not worry about it.
Anyway, these new games, I have found, have suddenly had a bit of a boost in many ways... The games themselves seem to play pretty much the same as they did with maybe the odd difference, such as the disk speed, or even a few glitches within the game, such as the drawing did not quite go right, and so a door might not render quite right, or you can see through a wall etc... nothing Major, bot one looking for this sort of issue now, they have gone, so overall, its been a great improvement for me.
Right now, I am swapping over between Linux and Windows and if I had to drop one, it would have to be Linux, but right now... Linux is getting closer and closer each distro.
After playing with Mac, I am struggling to understand why people like the bloody things so much...
