However, to me it's nothing significant enough over 7 on a gaming rig and I would just rather use third party apps on a mature OS than deal with hardware issues you can face on an immature OS. That's coming from someone who used 8 from release and rolled back to 7 a matter of weeks ago on their main rig.
To be fair gamers like us don't get much new (gaming wise)with every new OS,maybe a new DX version thats about it,nothing much more they can really do for us(unless you count free games in Microsoft Store).
As a gamer myself I have thrown a lot of games at Win8.1 with my Nvidia card from XCOM-Apocalypse(1997 game so pre Win98) using D-Fend to very latest ones like Divinity Original Sin (brilliant game) with no issues.
I even have a laptop with Win8.1(came with Win7 preinstalled) and not had any issues with that,I've thrown Intel,Realtek,Ralink,Nvidia,Asus,Atheros drivers at it to name a few with no issues.
Basically gaming with Steam,Origin,U-Play,Arc,Glyph etc has been solid for me even on my overclocked main gaming rig,gamers know what I'm talking about.
Right back to online gaming for me
