I've been having horrible lag whenever I move my mouse around at all after about 10 minutes of the game being open, the game lags both in game normally & in menus if I move the mouse, if I don't move my mouse but move my character I'm perfectly fine. HOWEVER most peculiar of all, if I hold my right mouse button down and move my mouse, there is no issue at all. I strongly doubt this is a hardware issue, none my my computer components used more than 50% usage & my GPU never got over the low 50s in temperature. I don't have this issue in any other game I play.
I have tried:
-Lowered Gamer Graphics to Lowest
-Turn off Motion Blur
-Change between windowed, windowed full screen, and true full screen
-Moved around various visual settings
-Grabbed a different mouse & tried that one instead
Updated GPU Drivers
My specs:
OS: Windows 10 (64-bit)
GPU: RTX 5070 TI
CPU: i9-14900KF
RAM: 64GB DDR5
Drive where game is located: M.2 SSD
Hey Hellfire702 — took a look at your log. Your report holds up, and there's some hard data in there that'll help.
Your FPS degrades exactly like you said:
t=1.5m 105 FPS
t=10.5m 103 ← right about when you said it starts
t=13.5m 74
t=16.5m 66
t=25.5m 47 ← less than half your starting FPS
And here's the useful part — there's a memory leak under it:
RSS 5523 MB → 6368 MB (+845 MB in 28 min, ~30 MB/min, climbing steadily)
Heap 2745 MB → 2642 MB (flat — GC is working fine)
The
managed heap is stable, so it's not a normal C# garbage problem. But
RSS keeps growing — that's
unmanaged memory (textures, meshes, native allocations) being created and never released. That's a real leak, and it's not your hardware. On a 5070 Ti / i9-14900KF you shouldn't be anywhere near 47 FPS.
The most valuable thing in your report is the right-mouse-button clue, and I don't think you realize how good it is. Free-look = lag. Holding RMB (aiming) = fine. That points at something running during the
look/hover raycast — the thing that figures out "you're looking at a door, press E" — which behaves differently when you ADS. Something on that path is likely allocating and never freeing.
Worth adding to your report (devs act on numbers, not descriptions):
- FPS degradation curve with timestamps (above)
- RSS growth rate with a flat heap — that's the smoking gun
- Explicitly say "unmanaged memory grows ~30 MB/min while the managed heap stays flat"
A couple of things that might narrow it down — if you can test:
- Does it still happen with no signs in view?
- Does it happen in a fresh world with nothing built?
- Does it happen in the main menu (mouse over menus, no world loaded)? You mentioned menus lag too — if it happens with no world loaded at all, that rules out anything world-related and points squarely at UI/input.
That last one is a really strong test. If it lags in the menu with no world, the bug is in the UI/input layer, not the game world.
Good report — you gave them more than most people do.
One thing i like you to try if you havent done maintenance in a while is this:
7 Days to Die Maintenance: Clean Game Files + Verify Integrity
Step 1: Make sure the Game Launcher opens
If you do not see the Game Launcher after clicking Play, you need to enable it first.
Right-click 7 Days to Die in your Steam Library.
Select Properties.
Under the General tab, find Launch Options.
Set it to Show Game Launcher.
Close the Properties window and start the game again.
The Game Launcher should now appear when you click Play.
Step 2: Clean game files
Start the game from your Steam Library.
Select Show Game Launcher.
Click the Tools tab.
Click Clean Game Files.
Check the circles/options you want to clean.
Be careful with anything related to saves, maps, generated worlds, or player profiles if you do not want to lose personal data.
Click Clean.
Step 3: Verify game file integrity
After cleaning game files, verify the game through Steam:
Right-click 7 Days to Die in your Steam Library.
Select Properties.
Click Installed Files.
Click Verify integrity of game files.
Wait for Steam to finish checking and downloading any missing files.
After this is complete, restart the game normally.
