Hmm I investigated why it had to keep clearing my game, so I had a look at my available RAM, it actually showed 2gb instead of my installed 4gb.
Long story short, I reinstalled the RAM and now the quick save is near instantaneous. It even changed the auto detect graphics from Medium to Ultra.
Guys, check your RAM, CPU-Z showed 4GB, but when I CTRL+ALT+DEL and looked at RAM it was stuck at 50% usage at base (available 2GB) which didn't make sense. The latest patch must've pushed the RAM threshold a tiny bit more where it had to clear memory to save.
Maybe there was a tiny tiny patch that I didn't know about that fixed it, but that's my story.
