THANK YOU SO MUCH! Let me just say that at most I notice a 5fps difference in favour of SLI 980Ti's in Heirarch Square, but in Frichlow you're 10 FPS faster in Patch 1.07. My cards were hitting mid 40's there especially near that damned Gargoyle spot.
I did notice you have more jaggies in Hierarch Square for some reason, and NPC texture popin is there. Although that's entirely down to CDPR's latest patch.
I have to say with hairworks enabled I'm really impressed, and I wonder if you've tried lowering the Tessellation in the Catalyst Control centre from x64 to like x16 time. Apparently that gives 90% similar visual with a good performance improvement.
All in all 'm really impressed with your cards, and by how well they're handling maxed out Hairworks. Seems that Xfire scaling is really helping.
I also notice a distinct difference in colour pallete between NVIDIA and AMD, although it might also just be down to cloud cover in your game at the time.
Here's my Hierarch Square screenshots at 12pm game time as well.
Now, if I do swap and get two Fury X cards I think I'll be rather happy. I'll just need to flog my G-Sync panel and get that lovely Asus FreeSync to replace it also.
