I've been trying to find a way to get LRR to work on my new PC for weeks now, after reading endless forums and discussions with AMD card users having the same problems as me, i would like to share how i got the game to run for me.
Specs:
PC - Alienware Aurora R4
Video Card - AMD Radeon HD 8990
OS - Windows 7 Ultimate 64 bit
Processor - Intel core I7-4960X CPU, 3.60GHz, 3601Mhz, 6 cores, 12 logic processors
