memory bound drops also manifest themselves with max GPU load. only way to properly identify them is to take a look at shared VRAM usage which alex is refusing to do so for some reason
it is why 3070 also performs greatly lower than ps5 at equivalent settings/resolutions because it is offloading 4.5 gb worth of memory to regular RAM. this is something PC games should not do, and instead do proper texture streaming. in most other cases, even breaching past 1 gb of shared memory will cause insane performance problems and you stop getting your GPU's worth of performance at that point
if a game uses more than 1-1.5 gb shared memory, it means that you're not getting optimal GPU performance you can get. simple as that. alan wake 2, avatar and most UE5 titles properly stream textures and never go above 1.5 gb shared memory and as such, in those games these GPUs perform like you would expect.
this war will go on because some of you people use this to opportunistically claim PS5 is punching above its weight when you know that all along an 16 GB 3070 would drastically change the result. hence the idea that ps5 performing better than the "3070" chip is just disingenious when the chip is being
stalled because of poor memory management decisions by the developer.
