I've seen a lot of people fight with AMD Crossfire issues with AC. Obviously its not fully/properly implemented yet but I'm about to start testing ALL the available profiles in CCC Omega over the next day or three (large jar of coffee at the ready). Looks to be a few hundred in total. Rationale: I play DCS flight simulator a lot. Just like Assetto (but DX9) there is no pre-defined profile for Crossfire in CCC & many users get frustrated in finding workable settings. However after doing some testing and going through the usual suspects of FSX, Rise of Flight, racing simulators etc I discovered the Dead Rising 2 profile gave me a 20%-30% boost in framerates (6 screens at 5760x2160p) over the aforementioned profiles and was also smoother with less framerate variation. Its nothing like DCS apart from being DX9 (much lower draw distance, different engine, slightly more zombies) but it works. I know a lot of people have done testing of profiles for AC in CCC but I haven't seen anyone do a full sweep and post results (please correct me if I'm wrong and save me the hassle and embarrassment). I have started going through random profiles already and have seen some variation so I've decided to make a list of all results and post them here for others to use in their own testing on their rigs as a base guideline. What I need to begin: 1) Suggestions for a base graphical configuration in AC (it wont be possible for me to test every variation of settings with every profile. I'd die of old age 1st). I can't start everything on ultra as some of the ultra effects are still likely very WIP for Kunos & doing this won't help those with lower spec GPU's with testing as they may run out of horsepower or vram so I need your opinions on settings. 2) A track, drivers car and opponent car(s) (full grid). For this I need suggestions for a drivers car known to be in a stable dev state (no quirks or issues known to cause fps variances) and is not open top so it produces in cockpit reflections etc. I'm also open to track suggestions. Please state reasons based on the games car/track graphics characteristics for your choice ("I love X car" doesn't count). 3) Any other suggestions you have to help with testing (including if I'm retarded in doing this). My specs are fairly high end so I should be able to limit the variances to profiles only GPU: 295x2 4gb (so 290x Crossfire) at 7680x1440 CPU: i7 4790k Stock RAM: 32gb DDR3 Dominator at 2133mhz AC on SSD to avoid HDD stuttering issues, if any. Due to time restraints I will only be able to take results from the game starting at the start grid until about 10 seconds into the race (cars will have moved off the line so smoke, reflections etc will have time to cause variance). I will screenshot every profile result. Thoughts ladies and gents?
