RADAR_PRE_LEAK_64

Question

My games occasionally freeze or stutter for just a moment, and this happens across multiple games. They don't crash, and I don't notice any other issues. However, I consistently see a 'Windows Error Reporting' event with the name: RADAR_PRE_LEAK_64.

Can someone

my specs are:
CPU: Ryzen 7 5700X
GPU: ASUS RX 9070 XT Prime
RAM: Kingston fury 2x16gb 3200mhz
PSU: TUF gaming 850W
MOBO: TUF B450M-PRO GAMING

Here is an example error with the game MH:wilds (similar messages for other games)

I would appreciate any help figuring out what is causing this.

Thank you

Answer 1

Jack,

Thank you for the information. I've asked that specific step to remove the ram stick for testing purposes only a part of the isolation.

these are additional steps to do.

1. Roll Back AMD GPU Drivers (if you have the latest WHQL driver )
   • Roll back to a known stable one, like 24.3.1 (March 2024)

Use DDU (Display Driver Uninstaller) to fully clean out the current driver before reinstalling.

2. Set Pagefile Manually

Set Virtual Memory manually:

a. Search "Advanced system settings" → open it

b. Under Performance → click Settings

c. Go to Advanced → click Change under Virtual Memory

d. Uncheck "Automatically manage..."

e. Select your system drive (C:) and choose:

 - Custom size

 - Initial: 16384

 - Maximum: 32768

f. Apply → Restart

3. Disable MPO (Multiplane Overlay) Windows 11

A known cause of frame dips and memory-related glitches.

Disable MPO:

a. Run regedit

b. Navigate to:

   HKEY\_LOCAL\_MACHINE\SOFTWARE\Microsoft\Windows\Dwm

c. Right-click → New → DWORD (32-bit) → Name it:

  OverlayTestMode

d. Set value to 5

e. Reboot

This helps fix frame inconsistencies with high-refresh monitors and Radeon GPUs.

Can I also confirm the current BIOS version. please include it to your next reply.

Answer 2

My problem isn't that games crash it is the fact that my games are stuttering, but the amount of stutters/freezes makes some games unplayable.

It happens across multiple games which some might require as little as 2gb ram or games like mh:wilds which takes up more.

removing ram sticks does nothing the problem still persists,

on a game like mh:wilds where my usage is close to 90%, I do notice a large drop in usage during the stutters (dropping from 90%->60 or less for just a second)

Answer 3

The RADAR_PRE_LEAK_64 event is a diagnostic alert, not a crash. It's often caused by DirectX 12/Vulkan games temporarily holding onto memory inefficiently. On systems with plenty of RAM (like yours: 32 GB), it doesn’t usually break anything, it just causes occasional hiccups or stutter.

Try to remove the other 16gb ram stick and play your game again. (testing purposes)

Answer 4

1. My drivers are all up to date.
2. All of my overlays are generally disabled (I might turn some on just to see performance) and I don't have excessive amount of background apps.
3. No errors, I also ran the windows memory diagnostics and that resulted in 0 errors.

Answer 5

Jack,

It’s part of Windows Error Reporting (WER) that monitors for memory leaks or inefficient RAM usage in running applications.

RADAR_PRE_LEAK_64

"Windows has detected a potential memory leak in a 64-bit application."

Let's check few things here and see.

1. Update All Drivers
   • GPU: Use AMD Adrenalin to clean install latest drivers.
   • Chipset: AMD B450 chipset drivers (most important)
   • BIOS: Update your TUF B450M-PRO GAMING BIOS if you haven’t already.
2. Disable Background Apps

Apps like discord overlays, steam overlays, RGB controllers, etc. can cause memory bloat.

a. Press ctrl + shift + esc → task Manager → startup tab

   disable unnecessary startup items.

b. Try running the game with overlays disabled (Discord, Steam, etc.).

e. Run System File Checker

Just to rule out corrupted OS components:

a. Press Start, type cmd

b. Right-click Command Prompt, choose "Run as administrator"

   enter command:



   sfc /scannow

Then:

   DISM /Online /Cleanup-Image /RestoreHealth

Let me know once done so I can assist you further.

Regards,

Iggy
