As mentioned in the change, the reports are inconsistent enough to be unreliable and the inclusion of it in the section has no real informative value other than as unnecessary speculation.
Saying that it is potentially caused by a memory leak helps nobody -- especially not when reports are widely different with users of 4 GB of VRAM and 8 GB RAM reporting minor number of crashes and people with 64 GB of RAM reporting multiple crashes.
That whole "High memory usage" section in itself is technically also problematic as "unexpectedly high [...] usage" is a subjective statement to begin with when there is no official baseline to compare again. Further on, the references listed is filled with counteracting reports further questioning its inclusion on the wiki page. But so far I have looked past it while at least trimming the more speculative parts of the section while waiting for further development on how to proceed.
Further on, based on testing by myself as well as, again, reports from other users it is not even guaranteed that the crashes the game experiences is caused by the memory usage, and we have yet to actually see sufficiently reliable reports or findings that actually suggests the memory usage is an issue as well as what is might cause.
Like, take my last session just now where I played the game for more than two hours -- no crashes, no issues, only about 3 GB of RAM used towards the end of the session.
It's basically speculations everywhere combined with clueless users whom might not even know what they're looking at and so blames "unexpectedly high" (what does that even mean without a baseline?) RAM usage when crashes caused by unexpected D3D12 results causes the game to "crash". Like really, you can't even manipulate the number of back buffers used by the swapchain without the game going "Oh my god, this is unexpected! I believe I have crashed!" when in reality it would function just fine. It's more than likely that half the crashes experienced by users is due to the game's fucked up D3D12 usage that treats any minor unexpected result as a "crash".
Random tangent over -- What will most likely happen is that when further evidence or confirmed reports arise we'll remove that whole "high memory usage" section and throw it under a general-purpose "the game crashes" section instead. But we're not there yet, and so we need to minimize the speculation present in the PCGW article.
On another note, I'm still waiting for a reply from you on Rose's talk page in regards to in what way the game isn't "proper HDR".
On a third note, the talk page of the article is for these kinds of discussions -- not individual editors/administrators talk pages.
