MEMORY ISSUE is for real !!!

[roZin1401]

3070 @ 1600p. High preset, fps is fine 70s right after starting the game and playing in the open areas until after entering a crowded village area, the fps drops significantly to 20s. Now i first thought this might be due to my card not being powerful to render all the assets and also due to 8gb being too low for 1600p even if DF stated it'll be fine for 1440p/1600p (i think he only tested non crowded open areas with less objects to render).

So i quit the game. started again after a while, the game loading the save with same crowded area. And now....... its at fluid 70s. The same crowded area at 70 fps instead of 20s previously. If the above said reason were true it should be 20fps no matter game was booted just prior or traversed to that area from open areas. So afaik, as my brain evaluates, this should be a case of a memory management issues happening. I don't see any other reason for why this happens. It seems like old assets that are not in frame are not being cleared from memory properly. And that with the directstorage streaming inefficiently might be the reasons. The last console port i experienced with a memory leak was back in 2013 for Prototype 2 PC port (actually it was a severe one). I hope Nixxes have already acknowledged this and working on it. Expecting a patch fix soon......

Currently Ratchet and clank, Spiderman ports shows memory issues, if not similar.

All others games i've played in my entire life gives a constant fps value for a particular resolution, graphics settings, in a particular location in-game. Regardless if just booted up my pc or after some hours of gameplay or if i'm in antarctica or in the arctics, wherever...... It may only change a tad bit 2-4 fps if the temps rise, and doesn't plummet to the 20s from the 70s like this game do.

EDIT:- Played longer after booting the game in the village settlement. fps is fine for then. Did some missions that requires to go to open areas far from the village, fps stays fine with the well known cutscenes fps drops, and i return back to village and the previous case happens again. Drops to slideshow 18s - 20s. So definitely a issue. Just double-checking.

Edit2:- As others reported here, if your cards with more than 8gb doesn't have any such issues, it might be because that amount of vram is fine for the memory issue to affect it (for a particular resolution). And doesn't mean that game doesn't have this issue. Nixxes probably should improve their memory management to fix this. I'm not telling the game infinitely fills the vram as the word "leak" usually mean filling vram/ram infinitely and ultimately CTDs, but that memory management is not good currently.

Looks like I've found why some users gets affected but not others even when both have the same 8GB gpu. Its HAGS!! Hardware accelerated scheduling was enabled in my PC and that's what causing degrading performance over time. Tested thoroughly with it turned off. Also why few people advice to turn it off for HFW and i thought they were placebo. If you have an 8gb card and no issues you probably have HAGs turned off. I think for now I'll enjoy this game with it turned off.

NOTE: Turning hags off can disable frame generation functionality for 40xx cards

You still want to praise nixxess ports????

Same issue here on my 3080. Nothing seems to fix it from reducing texture quality to turning of hardware accelerate scheduling.

I have a Ryzen 9 5900X @ 5GHz, 32GB DDR4 3200MHz, RTX 3080 10GB, Win 11 Pro with latest GameReady drivers playing at 3440x1440 max settings no DLSS or DRS.

Everywhere upon start, its around 70-80 but after some time It'll drop to 50-60 fps and stutter a lot. The cut scenes also become a stuttery mess after awhile. Restarting the game fixes it.

There is definitely a memory leak on both on the GPU side and system side. I've noticed on a couple of occasions, the game will suck up 26+ GB of system RAM for no reason but a restart of the game fixes it.

Weird, I've been playing for 50+ hours already at 1440p native (max settings with TAA enabled) with no upscaling, no dynamic resolution and no frame gen whatsoever at a rock-solid 130-180 fps (for responsive mouse control) including cut-scenes but a couple of busy, intensive ones that dropped to around 105 fps for a second. RAM never exceeds 10 GB usage while VRAM hoovers at 9-11 GB depending on location. Zero stuttering so far, not even a single frame time hiccup.

Specs: Overclocked 5800X3D (-30 all-core) and undervolted 4080 (2895 MHz at exactly 1 volt, VRAM +1500), DDR4 CL16 3800 MT/s 1:1:1, Samsung 980 Pro Nvme M2 Gen 4, W11 Pro fully updated and debloated. Optimized BIOS, G-Sync panel,
latest drivers installed after using DDU to uninstall the older set.

I forced resizable BAR enabled through profile inspector though (options xx1, xx1 and xx6 from top to bottom).

i buy tthis game today too, i realy liked the first one. But i hope the devs continue fixing bugs and improve the gane further so sutch stuff dont happen.

[Sinophile]

They just released a patch earlier today.

Exactly the same problem than OP on my friend machine with I7 10700K, RTX 3070 8GB VRAM and 32GB RAM (nothing OC). He can play at 60fps locked (vsync) a long time and suddenly fps go down to around 20/25fps. Sometimes, lowering Texture to Medium and then back to High is enough to fix the problem. But every time, restarting the game fix it for good, until the new time later.
So something seems not cleared/flushed properly, or RAM, or more probably VRAM is too fragmented and can't store a new asset.

I have a very similar system and am experiencing this issue as well. Also fps tanks in cutscenes but buttery smooth in actual gameplay till all of a sudden its a slideshow. Really irritating.

I had this kind of issue and found that it was caused by an old version of Rivatuner. Updated to the latest version 7.3.6 fixed it. Cutscenes can still drop to a low fps but normal game is fine now.

Woah. Thats a very unexpected conflict. How can a 3rd party monitoring tool break a games fps while in crowded areas. i just dont understand hows that even possible ????

Someone test this and report please.

I don't think that's a memory leak. Probably your 3070 not having enough Vram.

1600p High preset will be too much for only 8GB of Vram, which is why you can play for a little bit before your Vram get saturated.

80% of the time, these topics are created by RTX 3070 owners, and it's ALWAYS the same problem.

Restart your game, use the medium preset and you should be fine. Anything higher than 1440p with high (or higher) settings will be a problem with 8GB of Vram.

Tested with medium settings too. fps tanks whenever theres a settlement areas to render. Also i have stayed at this settlement areas for longer, after restarting game, (like nearly an hour) to see if it degrades but it doesnt. fps degrades only when i travel outside and come back to the settlement.

On a way more less powerful GPU and I've made this little post on how I improved things on my own, including the memory leak.

Just keep textures in medium if you have 8gb of VRAM.

[Medusa]

It's only a leak if the usage keeps climbing forever, which is not the case.
Extended play sessions may show increased usage but not something that keeps climbing forever.
So my bet is there is no memory leak, it's just folk trying to justify their 8 GB being enough.
From what i can tell Digital Foundry is quite the commercial outlet and doesn't really have time to test older cards for hours to see if memory issues will eventually come up.
Still though, VRAM overflow is a delicate thing that sometimes can only crop up after like an hour of play. Still doesn't mean it's a memory leak.
If there was actually a leak the complaints would be worse and more widespread.
Because if it was a leak even the 4090 would eventually go beyond it's framebuffer.

I believe that is wrong. if the character stays at a location and fps is fine, that's because there's nothing new to load into vram to saturate it. data gets streamed while travelling through the world. So if the same place after some travelling now gives a lower fps its obviously cause of improper vram usage by the game (for assets). It should release unused data.

If the game didn't have any memory leak issue, and 8gb cards gets low fps for the said area, then what you said would be true i.e. no matter the game was just booted up or after x hours of gameplay it should have the exact same fps for an area rendered. But evidently that's not the case. i and as others reported here, we get good fps right after booting up/restarting.

if you have no issues, it might be cause you have too high/good amount of vram (for a particular resolution) for the memory leak to affect you.

just delete the dstorage.dll & dstoragecore.dll in the gamefolder. this fixed all my performance problems. no fps drops in cutcenes or crowded areas. playing on high settings @1440p with a 3070ti & 5800x
