I've been dealing with a bit of a conundrum with gameplay on my new iMac at home vs. the one I use at the office. The old one is a 2013 iMac. Gameplay feels smooth. Occasionally when I launch and play COD, it for some reason runs in a higher detail mode but the action is really laggy. So I'll quit and relaunch maybe 1-3 times until it snaps into the lower detail mode but actions is snappy. So if you see me log in and quit a few times in a row, that's why. I can live with that glitch.

The thing that's bothering me with my shiny new one with faster everything (processor/graphics/bus, etc) is that no matter what I do, I can seem to make it "feel" like my other machine as far as play action. The screen motion makes me dizzy and the response doesn't feel snappy like my other machine. I've tried making the settings 1:1 with the older Mac as far as graphics and texture, etc, but it's still off. I'm assuming the architecture of the newer iMac is not interpreting the settings the same way. I've tried dropping game graphics resolution, cranking detail way down, or way up, mouse sensitivity, etc. Anyone out there have any suggestions? On both Macs I have the same Kensington Expert Mouse trackball. I updated the driver on my home machine over the weekend and that did help somewhat with the Look action. But the motion in game still makes me feel dizzy when playing.

Thanks,
Greg

P.S. Both iMacs are 27" screens. The new one has a native screen resolution of 5k.

I had the same problem switching from my very old pc to a much newer one with all high spec everything. I wanted to match the feel of the gameplay like it was on my old rig. I've found it to be nearly impossible to recreate that same gameplay. What I have learned was that the 'snappy' feeling was me not seeing every frame of gameplay like I do now. The game appears to be much slower but smoother at the same time. I ran the game at 125fps on a 60hz monitor on my old pc and on this newer pc I run it at 333fps on a 144hz 2k monitor. Although I don't use it at 2k for the game because the game doesn't support 2k. Whatever your monitor is make sure the settings match the ingame settings (hz and resolution). At first I had the ingame settings at 60hz and my monitor at 144hz and the game looked all funky and choppy until I realized I needed to make the game setting to 144hz. I'm still adjusting to the new setup and I am really enjoying the ability to be able to jump over people.
