Reporting back.
After doing some checking with my graphics options and some long, long testing I think I have found a way around this sort of crashing.
Antialiasing was causing the crash.
It was set to 2x MSAA, after disabling it I was able to play in the test range for a good 15 minutes. Going to load up a multiplayer server now and I will report back!
You know one thing that really pisses me off, how bad a multi billion dollar support system can be. Absolutely shocking. I've been playing BattleField games since 2002, 12 years later you still treat us like something you would find under your foot. EA does not care about us at all, shame they're missing one thing - we give them their wages, their player base. Perhaps they should remeber that.
You think I'm buying BF HardLine? Think again.

Able to play for 43 minutes, still no crash. Looking good. Doing a map swap now, shall keep updated.

Able to play three maps, no issues. Good FPS, game still looks very pretty. Hope this can help other people out there!
