Massive bug in Epic Games Launcher VRAM Usage

It has been a month since i noticed it and i can’t believe nobody have reported it yet, since a month or so(it might be more) the epic games launcher started using 4Gb of VRAM after launch, NOT system RAM, VIDEO RAM, GPU RAM, whatever you want to call it, the dedicated memory storage for the graphics card.

I have tested it on my Tower pc, an old laptop and my new laptop and also a completely fresh install of windows with just drivers and the Launcher, ALL present the same issue, after opening the launcher it just starts eating the VRAM, and does not even respect the iGPU vs dGPU priorities, all my other programs go to the iGPU shared memory, but the Epic Games Launcher goes DIRECTLY to dGPU VRAM, it goes from 0 to 4Gb by ONLY opening the launcher.

After some investigations and tests i have discovered that it happens on logged in accounts, if i SignOut it frees most of the VRAM(still uses around 300-500Mb of VRAM just in the login screen), and if i login again it starts to eat the VRAM for breakfast again…

Hi there,

Thanks for letting us know about this issue. I have passed it along to our development team for an internal review.

Same problem here I get 3 Gb of VRAM Use from Epic Launcher, even running in the background, any fixes Yet ?

God 4gb it’s insane! I have 2.5gb use.

Any news on this? It’s still there, how are we supposed to play games when up to 90% of the video memory is already used for just the launcher… 8Gb(in my case) is already on the limit of not being enough, slicing that in half has BIG impact on performance, makes play any games on EGL a very bad experience…

When i reported the bug it was already happening for like a month or two(since i noticed), how is that an so impactful problem like this not receiving any attention for such of a long time?

It hasn’t been updated for a month.

Hello all,

Thank you all for reporting this issue and your experience! I’ve made the appropriate teams aware of this issue and we’re actively investigating this. We consider this a high priority issue, so expect an update on this in the near future!

If you haven’t performed any troubleshooting, I recommend starting with this article. These steps could alleviate some of your issues while we investigate, so I encourage you to try them if you haven’t already.

Look forward to receiving an update on this!

Hello,

Thank you for your patience! We’ve been actively investigating this issue but could use some assistance from you all to identify this issue. If you’re able, please help us investigate this by gathering the following info:

  • A screen recording of the Task Manager > Details Tab, with dedicated GPU usage for EpicGamesLauncher.exe (you may need to add the column for Dedicated GPU Usage in the Task Manager)
  • If you’re able to record this both while logged into the launcher and while not logged in, that would be very helpful! We’d like to see the pattern of growth of the VRAM consumption
  • Lastly, we need a copy of the Launcher logs. You can find these by clicking on your account in the top-right of the Epic Games Store Launcher, select Settings and select Show Logs. Selecting this should automatically take you to the Logs file location.

Once you have this information, please provide a Google Drive URL so I can get this to the appropriate team.

Thank you all for your help and cooperation! We want to do everything we can to help. I look forward to hearing back on this!

  • Windows 10 doesn’t have the dedicated GPU tab (I use it)
  • Being logged in or logged out does not affect

Hello Jinkel,

Thanks for providing this info! On my personal computer, I was able to add the “Dedicated GPU Usage” tab to the Task Manger > Details Tab by right-clicking on a column and selecting Select Columns from the menu. The option for “Dedicated GPU Usage” is near the bottom. If you’re able to gather a recording of the Task Manager > Details Tab while opening the launcher, that would be a huge help!

Additionally, we’re looking for more information about affected users’ setups. Could you please describe your setup for us? Multi-monitor, OS and version, or anything you would consider unique to your setup would be very helpful to know!

Lastly, if you’re able to gather a DxDiag of your device, this would help our teams immensely.

I look forward to hearing back from you!

I thought it was fixed with this recent Epic Launcher update…

Hello,

Thank you for sending that over! We’ve not been successful in reproducing this issue at this time. Additionally, we’ve looked at the logs and nothing seems to be sticking out as an obvious cause.

If you’re able to provide a screen recording of your experience and the Dedicated GPU Usage in the Task Manager, that would be incredibly helpful! We want to resolve this as quickly as possible, but to do so, we’ll need to find some way to reproduce this behavior. This is why the video would be so impactful for this investigation.

I look forward to hearing back on this!

On Reddit a user said it could be Unreal Engine but I don’t know. Other programs don’t consume that crazy.

Hello,

Thank you for sending this over! I’ve passed it along to the team that’s directly investigating this issue. I’ll see if there’s any additional data points we need at this time and I will provide an update as soon as possible! Thank you for your patience while we continue to look into this!

Noticed this too. About 1gb of vram usage in background. Takes away the little headroom I have while using UE5.

I also have this same problem, on my system with an old AMD Radeon GPU with 4 GB of GPU VRAM, epic launcher always uses ~2GB when running. I have also seen this behavior on a Nvidia (Ampere gen) laptop GPU (also ~2GB used out of 4GB VRAM), though not on all program launcher.

This roughly started around a month ago, before that EGL used the “normal” 0.1-0.3GB amount that chromium/CEF/webview/etc usually uses on VRAM (i.e. the same as every other “modern” program).

Sometimes it is possible to make Windows swap out the memory to system RAM, making the launcher use an extra ~2GB of CPU RAM instead (and eventually swapped out to the on-disk pagefile). Meaning that games can finally actually use the whole amount of VRAM.

Still same problem, even after the update of the other day, is it so difficult to debug/fix?

I just created another fresh account and added some free assets from FAB to finally clear my initial guess that is the owned products that inflate the VRAM usage, and i was completely right, that completely explains why people have their VRAM fill up to different values and there is not a million reports, because the VRAM usage is proportional to the products owned(don’t know if it’s games+assets or only games OR assets).

My account uses over 4GB of VRAM, fresh account with some products just around 130MB:
