GPU memory leak on the ASUS ROG Strix SCAR 17 i9-13980HX means VRAM usage increases over time during gaming or GPU-accelerated tasks, eventually filling the RTX 4090 Laptop 16GB VRAM and causing game crashes, stutter, or driver crashes. This is most commonly caused by a specific NVIDIA driver version that has a known VRAM allocation bug, or by a DirectX 12 game with an unpatched VRAM leak interacting with NVIDIA's memory management on Lovelace Laptop GPUs.
Fix 1: DDU Clean Install Latest NVIDIA Driver
Download Display Driver Uninstaller (DDU) and the latest ASUS-certified NVIDIA driver for the ROG Strix SCAR 17 G733PYV from ASUS Support. Boot into Safe Mode, run DDU to remove all NVIDIA driver components, restart normally, and install the new NVIDIA driver. DDU removes all residual driver files that a standard uninstall leaves behind, preventing the memory allocation bug from carrying over from the old driver version.
Fix 2: Disable Hardware-Accelerated GPU Scheduling
Open Settings → Display → Graphics → Change default graphics settings and turn off Hardware-accelerated GPU scheduling (HAGS). HAGS transfers GPU memory scheduling from the CPU to the GPU itself. On certain NVIDIA driver versions for Lovelace Laptop GPUs, HAGS has known interaction with DirectX 12 memory management that can cause VRAM not to be properly reclaimed between scenes, producing an apparent memory leak.
Fix 3: Roll Back to Stable NVIDIA Driver
If the memory leak started after a driver update, roll back via Device Manager → Display adapters → NVIDIA RTX 4090 Laptop GPU → Driver → Roll Back. Check NVIDIA forums or the ASUS ROG community forums for the specific driver version that introduced the VRAM leak on RTX 4090 Laptop. Some driver versions (particularly early Lovelace driver series) had documented VRAM allocation issues that were fixed in subsequent releases.
Fix 4: Close Background GPU Processes
Open Task Manager → GPU Memory column. Identify applications using significant VRAM in the background. Chrome with hardware acceleration, Discord, and OBS can each consume 200–800MB of VRAM. Close unnecessary applications before gaming sessions to leave more VRAM headroom and reduce the speed at which a VRAM leak fills the 16GB capacity on the RTX 4090 Laptop GPU.
After a DDU clean install of the ASUS-certified NVIDIA driver on a SCAR 17, the VRAM usage stabilized and stopped climbing. The previous driver had a known HAGS-related VRAM issue on RTX 4090 Laptop GPUs. Disabling HAGS as a secondary fix further reduced the baseline VRAM consumption during heavy gaming sessions.
Per Hazwan Nazri, competitive gamer and content creator on ROG Strix SCAR 17: “The GPU memory leak causing game crashes on my SCAR 17 was a known NVIDIA driver bug. DDU clean install with the ASUS-certified driver and disabling HAGS completely fixed the VRAM climbing issue.”
Frequently Asked Questions
What causes GPU memory leak on ASUS ROG Strix SCAR 17?
The most common cause is a specific NVIDIA driver version with a VRAM allocation bug, or HAGS interaction with DirectX 12 on Lovelace Laptop GPUs. Perform a DDU clean install of the ASUS-certified NVIDIA driver and disable Hardware-Accelerated GPU Scheduling in Display Settings.
How do I monitor VRAM usage on ASUS ROG Strix SCAR 17?
Install MSI Afterburner with RivaTuner Statistics Server for an in-game VRAM overlay. GPU-Z shows real-time VRAM usage in the Sensors tab. Task Manager GPU Memory column shows per-process VRAM allocation. A memory leak appears as a steadily increasing VRAM value that does not drop when scenes change.
Does disabling HAGS affect gaming performance on ROG Strix SCAR 17?
Slightly. HAGS can improve frame pacing and reduce latency in some DirectX 12 titles. Disabling it may cause very small frame time increases in some games. For the ROG Strix SCAR 17 with its high TGP RTX 4090, the practical performance difference is minimal and the stability improvement from eliminating the VRAM leak outweighs the marginal frame time change.
Can a game patch fix the GPU memory leak on SCAR 17?
Yes. Some VRAM leaks originate in the game engine rather than the NVIDIA driver. A game-side VRAM leak is fixed by a game patch, not a driver update. If the VRAM leak only occurs in one specific game while other games are stable, the leak is likely in that game and a developer patch is the only resolution besides closing and restarting the game during long sessions.
Conclusion
GPU memory leak on the ASUS ROG Strix SCAR 17 i9-13980HX is most reliably fixed by a DDU clean install of the ASUS-certified NVIDIA driver from ASUS Support for the G733PYV. Disable Hardware-Accelerated GPU Scheduling in Display Settings as a secondary fix for HAGS-related VRAM allocation issues on the RTX 4090 Laptop. Monitor VRAM usage during gameplay with GPU-Z or MSI Afterburner to confirm whether the leak is resolved after the driver change.
