Memory leak for 30 series cards is STILL present.

[Yeti]

I have to restart the game every hour or two. Upon starting I get ~130fps on 144hz 1440p monitor with a 3080ti. Around 45 minutes later the frames and gpu usage slowly decline until it becomes unplayable. CPU and memory usage stays consistent. This bug has been here since launch, even with updated Nvidia drivers. Please fix!

My 3080 does not do this. FH5 plays constant at 115/125+ fps @ 3440x1440 depending on map location & does not decline over time. Maybe the issue lies elsewhere OR possibly is specific to your gpu model

"This problem named: Memory overflow is another cause of the LOW FPS issues after playing Forza Horizon 5 for a while. This can be fixed by increasing the paging file. RIght click windows start menu, select Run. Type “advanced system settings” and open this app > click “settings” under Performance > Advanced tab > click ‘Change’ under Virtual Memory > uncheck “Automatically manage paging file size” > check Custom size and set 8192MB for Initial Size and 16000MB for Maximum and hit apply. The paging file size I’ve mentioned here are for at least 16 GB of RAM. This will fix the low FPS issue with FH5."

Important to note is to do this for the drive FH5 is installed on. If you have your game installed on a drive other than your windows drive and you increase the page file of your windows drive, it'll do nothing. In my case, I have a dedicated drive for games, so I had to create the page file for it. I haven't had any slowdowns since.

ya i have a msi 3080, after about 30 mins of racing i get cpu bandwith warning, i restart and im back to 144fps. I know for a fact its not on my end, if it was restarting the game wouldnt fix the problem.

I already have that maxed out on my ssd, didnt work, its a known issue.

2080ti suffers the same issues, only the game won't even use more than 16% of my GPU at any one time, with constant performance degradation over time as I play.

[cyäegha]

that's probably because it likely isn't actually a memory leak
people keep parroting the term as though they know what it means or what real-world performance implications it has, and the demonstrable performance decay over time isn't consistent with how a memory leak works

if you have a memory leak, performance doesn't steadily decline like we've been experiencing thus far, your performance stays consistent right up until the moment you run out of free memory, at which point your performance absolutely tanks because it's having to write addresses to your pagefile
if that isn't large enough, or the drive isn't fast enough to cope with the sudden memory dump, the game crashes

the same thing happens with VRAM, your performance doesn't steadily decrease over time, it keeps on keeping-on right up until you run out, at which point it's swapping to onboard RAM, which is considerably slower
that can then have a knock-on effect of consuming more system memory and potentially contributing to the former
given that - both from my experience and what i hear - GPU utilization rarely, if ever, reaches 100%, i'm inclined to believe that the problem is something more basic at the engine level
that isn't to say that there isn't a memory leak, there most probably is, but it doesn't seem to be the root cause of this problem

that's... not how pagefiles work, or what they're used for
pagefiles are an emergency measure to prevent your system from crashing when it runs out of addressable memory, not VRAM
this used to be more common before everyone and their mother started slotting upwards of 16, or even 32-gigs of RAM in their systems
some people, lunatics mostly, even disable the pagefile outright with no meaningful benefits or downsides other than the risk of their system crashing when it runs out of RAM

that said, putting one on the same drive as the game is immaterial given that the game doesn't interface directly with the pagefile, ever
again, this used to be more common before SSDs were a thing, and having multiple hard disks running in parallel would slightly speed up swapping, when it came to that
though you're right about one thing, increasing its size beyond the default settings will do nothing, because it's not meant to be used
if you ever find yourself having to use it regularly enough to micromanage the size of your swap partition, you're doing something horribly wrong

It can mean you don't have a custom page file set by yourself,

[1MantisPhoenix]

Are you using the new shader caches ?

[polu psilos gia na pethanw III]

My 3070 vision OC underclocked at 0.90v 1980Mhz Core, is doing fine at 120-130 fps 1440p ultra settings with no drops during long gaming sessions... maybe its some specific models or chips?!

[1MantisPhoenix]

GTX`1070 is also good over 3++ hours, nvidia caches are goood

Don't have this problems , but a bug when recoding a video.
While recoding with xSplit and starting to drive it says "Low Video Memory", after pressing "ESC" it continues without any problems.

I am using a Gigabyte RTX 3080 Gaming OC

See it at 0:59 in the video below

This is the most bonkers advise and explaination I've ever heard of.

[Azmodan19]

I'm not the one who came up with that solution. It did, for whatever reason, solve my instance of framerate drop.

[dismay]

So, no fix for a consistent decay of fps? Are you serious? Not even a mention of half the PC community complaining about it?

It seems to be affecting high-grade systems. Is anybody on a 10 series GPU getting this issue? I know someone with a 1080 and he has never had a problem. I personally have a 3080 with an i7 9700K and get major issues. Seems like some people with the 20 series are having issues as well? :L

Just keep the pagefile at automatic settings, there is no point doing it manually for any game. And completly turning it off, also is a bad idea, some old programs still have to use the pagefile for some reason. Even if you have 128 GB or something, you still need the pagefile active. If there is a memory leak a larger pagefile wouldn't help at all, you would still lose FPS if the RAM is full, the only difference would be that you don't crash. But how should that help, if the game runs like garbage then anyway, it wouldn't help at all.
