Thing is, I don't play Warhammer :) My iMac Pro has the Radeon Pro Vega 56 8 GB. I'm given to understand the absolute top of the line had some kind of problems… still, that's as much in graphics card RAM as exists in the whole RAM of some of the M1s. I'm betting Warhammer makes heavy use of the graphics card and it's that which is walloping the M1-running-Rosetta-emulation. This probably means there will still be games where a previous version with a fancy enough graphics card will get higher framerates than what the M1 Macs can get. I don't anticipate Apple ever making those kinds of concessions to the gamer market, so that's where you're going to see the only holdouts (in terms of, M1 doing super poorly). And that, mostly with stuff that expects real gamer cards. I don't think the Radeon Pro Vega 56 is nearly top of the line for a gamer card but I can easily believe it's better than the on-board graphics for the initial M1 machines. Remember part of the selling point for the iMac Pros is that they could summon up graphics-card grunt for the purposes of 3d modeling. I should try some Blender experiments and see what's snappier, there's a possibility the iMac Pro will make a decent showing for itself for that reason :)
