If they've got time, I'd like
John90976 to run the 5 minute in-built benchmark of Red Dead Redemption 2 which will reveal the true framerate that his iMac runs the game at and also give us a screenshot of his resolution and graphics settings used to run the benchmark.
No doubt this GPU option gives us an amazing GPU option finally. But I can't just take his account, that the TDP limited 5700 XT in the iMac is nearly at the performance level of an RTX 2080 Ti, at face value. One person's subjective experience of how it is performing doesn't make it actually so. That this iMac 5700 XT is somehow defying all logic to beat non-power limited RTX 2070 Supers and nearly equal the RTX 2080 Ti would truly be 'voodoo magic' if the benchmarks show it
