Tomb Raider has almost perfect scaling on 4 cards with both AMD and NVidia, there are a lot of other games that also have near perfect scaling on 4 cards.
Where it goes wrong is with lazy reviewers, you need to use a 4K monitor to test out 4 way scaling properly.
The other thing that will mess up 4 way scaling at high resolution is to use a 256bit bus, I think it is time to leave this thread quick.![]()
Indeed you need the right resolutions to get the most out of 3-4 way.
