A Forza Horizon 5 player reported system-memory use rising from 32 GB to 45 GB before the game crashed, but that single account does not confirm a general PC memory leak. The available evidence also does not establish a verified workaround for that specific symptom. If it happens on your PC, record the conditions and report the crash through Forza Support rather than applying fixes meant for a different GPU-related issue.
What the reported Forza Horizon 5 memory problem is
On August 25, 2024, a player named Enfentonk5486 posted the forum thread “Memory Leak? – 45/32GB system memory in use”. The player said FH5 displayed system-memory warnings while they completed weekly challenges. They reported usage passing 32 GB and rising through 37 GB and 42 GB to 45 GB before the game crashed to the desktop.
The player listed Windows 10, a Ryzen 5 5600X, 32 GB of RAM, and a Radeon RX 7900 GRE. This is one player’s account, not a controlled test or a developer-confirmed diagnosis. It does not establish how common the symptom is, what caused it, or whether other players’ systems are affected in the same way.
Does this confirm a memory leak, and is there a proven fix?
No. Rising memory use followed by a crash is consistent with a possible memory-growth problem, but one report cannot confirm that FH5 has a general memory leak on PC. The reviewed sources do not show an official confirmation or resolution of this particular August 2024 report, and they do not establish a verified workaround for it.

Steam’s current FH5 listing gives 8 GB RAM as the minimum and 16 GB as the recommended system requirement (Steam listing, accessed October 8, 2026). Those baseline requirements are not evidence that adding RAM will stop the reported upward usage or prevent a crash.
Why the NVIDIA driver workaround is a different issue
A separate PCGamingWiki entry describes a GPU-resource handling bug in which evicted resources are handled incorrectly, with newer NVIDIA drivers exposing a crash issue. Its search-result excerpt lists an NVIDIA Profile Inspector profile flag and rolling back to driver 561.09 or earlier as workaround options for that GPU-resource crash. PCGamingWiki is community-maintained, and the page could not be opened directly for verification.

That advice concerns a separate NVIDIA-related GPU-resource crash, not the reported growth in system memory on a PC with a Radeon RX 7900 GRE. It should not be treated as a fix for the memory-growth report. The available evidence does not support changing driver profiles or rolling back a driver as a remedy for this specific symptom.
