You know it's not accurate
Either some folks have their systems set up wrong or their 4090s are a bit busted? The most hardened GFX games out today (path traced) all run at 100fps+ when utilising all the modern tech RTX has to offer at 4K and some of us have demonstrated this in videos and RTSS screens plenty of times.
Unless by struggle people are referring to not being able ot get near 240fps for a 240Hz display, well no GPU will be able to do that in modern engines like UE5, the RTX 5090 won't even get there lol.
My personal view is that once you get top 100fps however that might be and with max GFX settings, you're in the best possible position.
Games at launch that are bugged or unoptimised do not count and people need to stop normalising this sort of commentary by claiming a GPU isn't capable because it can't run game x that just launched over 80fps at 4K etc.
As for RDR2, I actually forgot how that ran even though I installed it again a few months ago, so re-downloaded it and ran the benchmark:
Using 4K native, manual ultra settings inc advanced:
