That the bug is there for ryzen cpus on pc doesnt either mean its present on consoles. I have not bothered at all to change values (yet) as i have zero problems with the cpu (3950x), nvme ssd or ram. It feels the 2080ti is the limiting factor now. I would have gotten an even better experience with a 3080 or something.
The first Titan? Also a dinosaur Its the Kepler architecture which didnt focus on GPGPU as much as the generations before (tech sites even predicted trouble) or amds GCN and therefore didnt age aswell in games taking advantage of that. Still, its a almost 5TF gpu packing 6gb's of fast ram and is almost a whole year older then the PS4/OneS. Its a bad value anyway, compared to say if you had gone for a R9 290x......
The games is just using BC mode. This is not an optimized PS5 and Xbox Series game. It is probably worse than the Ryzen bug. I expect big gain on the CPU and GPU.
