i have it installed on my drive already. I have notice that if i play more then an hour it starts loading for a least 2 mins
And other Xbox users have already suggested "clear your cache" as the solution to that

And this not aimed at GNUT, but just a general response to the thread:
The truth, however much it hurts, is that people who have the cash to spend $1-2K on a PC gaming rig are going to get better performance than someone with a $200 console based on aging hardware - that's the way of the world, and yes in some ways it's not fair, but it's also a case of you get what you pay for. I've seen the in-game graphics comparisons between PC and Xbox, and tbh it ain't pretty. That's why people still play games on PCs, why people still pay good money for PC hardware, and if I run out of space for installing games I can easily bung in a new 2Tb HDD as my 3rd or 4th or 5th HDD and just carry on going.. people use PCs for a reason, yes they are more expensive and require maintenance, but there is a payoff which is why people do it...
