by the way check your dedicated gpu memory for game and see how much vram it uses (task manager, not afterburner). there's still possibility you're vram bound
reason:
the game, at max, will allocate 7-7.1 gb "dedicated" gpu memory to itself on 8 gb. and out of that 6.8-7.2 gb, the afterburner per game usage usually shows 6.3-6.4 gb vram (never goes above this value, like, never). in practicality, I'm VRAM bottlenecked at 6.4 gb per app vram usage on 8 GB. (%80 rule, similar to how spiderman "behaved"). for 10 gigs, this is 8 gb (and with some extra dwm usage, yours might be 7.5 gb) I will be VRAM bottlencked but per game vram usage will never go above 6.3 6.4 gb. this is super super similar how hogwarts + spiderman behaved.
here's what i mean
actually you can verify this. try to make your dedicated per game vram usage go above 7.5 or 8 gb. it won't. game has a hard %80 set fixed rule. it simply won't use more than that. total vram usage can be very misleading also (due to background clutter).
in task manager, dedicated gpu memory never goes above 7-7.1 gb for me. so that's the max game can "allocate". and out of that allocation, game will never go past 6.3-6.4 GB VRAM.
I've observed this weird mad rule with spiderman, reported to DF and nixxes, and they upped the allocation + usage percentages a bit and that helped.
I think there's simply a big miscommunication / problem / stuff that even devs are not aware. this is just resources left unused for no good reason at all.
so yeah, you're most likely vram bottlenecked while seeing 7.5-7.7 GB VRAM usage. becase by my calculations, that is where you would usually land on game's logic of using available VRAM
(spiderman also VRAM bottlenecked around 8 GB on 10 GB cards and around 6.4 GB on 8 GB cards).
it is time devs address this problem. them cards already have super duper limited resources as is. by putting such "relax" allocation percentages, they're actively hurting us for no good reason
this stupid rule, behaviour whatever it is, also misleads people as you think your problems have nothing to do with VRAM, whereas you do. you just see empty vram space and think the game is tame in vram consumption. it is super super misleading.
even if this behaviour is required for game operation, then I deem all 12 10 gb cards also obsolete. this means for this game, your 12 gb gpu is simply a 10 gb gpu. this is just too much limitation.
