How to Fix Forza Horizon 6 Low Video Memory Warning and VRAM Crashes

When I first launched Forza Horizon 6 on PC, I expected the usual open-world chaos: insane speeds, gorgeous weather effects, and late-night convoy sessions with friends. What I didn’t expect was spending half my weekend fighting Low Video Memory warnings, random FHD01 crashes, and weird stutters every time I opened a tuning menu.

And honestly? The frustrating part is that my hardware should have handled the game easily.

I’ve seen people with RTX 5080 cards, Radeon RX 9070 XT setups, and even absurdly expensive rigs getting the exact same issue. After digging through Reddit threads, testing settings myself, and comparing results with other players, it became obvious that this isn’t just a “weak GPU” problem. The game currently has some seriously messy VRAM behavior on PC.

So if your game keeps crashing after long sessions, textures suddenly become blurry, or the dreaded “Out of Video Memory” popup ruins your race, here’s the stuff that genuinely made the biggest difference for me.

Why Forza Horizon 6 Eats VRAM So Aggressively

The biggest issue right now seems to be how the game handles DirectX 12 memory allocation. During normal gameplay, VRAM usage slowly climbs higher and higher, especially if you:

• Fast travel often
• Enter garages repeatedly
• Customize cars for long periods
• Open upgrade menus constantly
• Spend hours in free roam

At first the game runs perfectly. Then suddenly the stuttering starts. Audio begins crackling. Menus freeze for a second. Eventually the entire thing collapses into a desktop crash.

It feels like the engine keeps storing old assets instead of properly clearing them.

What surprised me even more is how badly background apps affect the game. I tested this myself by leaving Chrome and Discord open. VRAM usage instantly became worse. The game behaved as if my GPU had less memory available than it actually did.

That’s why some players with 16 GB cards are somehow getting the same errors as people using older 8 GB GPUs.

The One Graphics Setting That Changed Everything

After experimenting for hours, I can confidently say this:

Environment Texture Quality is the real VRAM killer.

I originally had it set to Extreme because, well, why not? But lowering it to Ultra instantly reduced memory usage by several gigabytes while barely changing the visuals during gameplay.

At high racing speeds, you honestly won’t notice the difference unless you stop and stare at rocks for five minutes.

If you’re running an 8 GB or 12 GB GPU, keeping textures on Extreme is basically asking for crashes right now.

Background Apps Are Secretly Hurting Performance

This game absolutely hates unnecessary GPU usage in the background.

Before launching the game now, I close almost everything except Steam itself. That alone stabilized performance more than some driver updates did.

Apps Worth Shutting Down

• Google Chrome
• Discord overlay
• OBS
• Wallpaper Engine
• GeForce overlay
• AMD overlay
• Browser tabs with hardware acceleration

Chrome especially was surprisingly brutal. Multiple tabs running videos or streams can quietly reserve over 1 GB of VRAM without you realizing it.

Once I cleaned up background apps, the annoying stutters during city driving almost completely disappeared.

Clearing Shader Cache Actually Helped

Normally I’m skeptical about “delete your cache” advice because it often sounds like placebo troubleshooting. But in this case, clearing the shader cache genuinely reduced hitching.

For Nvidia Users

1. Open %localappdata%
2. Find the NVIDIA folder
3. Delete files inside DXCache and GLCache

For AMD Users

1. Open Adrenalin Software
2. Go to Graphics
3. Find Reset Shader Cache

After restarting the game, the first few minutes may stutter while shaders rebuild. But after that, performance usually becomes smoother.

The Paging File Fix That Stopped My FHD01 Crashes

This one sounds boring, but it probably saved my game sessions.

Because the VRAM leak eventually overflows into system memory, Windows starts relying heavily on virtual memory. If your paging file is too small or disabled, the game simply crashes.

I manually increased mine on my SSD and immediately noticed longer stability during marathon sessions.

Recommended Paging File Setup

A lot of PC players ignore paging files entirely in 2026 because modern systems have plenty of RAM, but some newer games still depend on them heavily when memory management goes sideways.

And right now, Forza Horizon 6 definitely qualifies as one of those games.

Handheld PC Players Have It Even Worse

I also tested the game on a handheld device similar to the ROG Ally, and honestly the VRAM behavior there is even messier.

The automatic VRAM allocation setting caused horrible issues:

• Audio crackling
• Random freezes
• Incorrect VRAM reporting
• Massive FPS drops

Switching the BIOS UMA Frame Buffer to a fixed 6 GB allocation helped a lot.

If you’re playing on handheld PCs like the ROG Ally, Lenovo Legion Go, or MSI Claw, don’t trust automatic VRAM allocation for this game yet.

Why FPS Caps Matter More Than You Think

This was another thing I didn’t expect.

Running the game uncapped at ultra-high framerates made the memory leak noticeably worse over time. My guess is that the engine streams assets much more aggressively at 120+ FPS.

Once I locked the game to 60 FPS, memory usage climbed much slower.

That doesn’t mean the leak disappears completely, but it delays the inevitable crash long enough for normal gaming sessions.

FPS Cap Recommendations

Going fully uncapped currently feels risky unless you restart the game frequently.

Driver Updates Alone Won’t Fix This

A lot of YouTube videos claim “latest drivers solve everything,” but based on my testing, that’s only partially true.

Yes, newer Nvidia and AMD drivers improve stability slightly. But the core problem appears to be engine-side memory handling rather than purely driver-related.

That’s why even people with brand-new GPUs are still getting VRAM warnings, texture corruption, sudden freezes, and desktop crashes after long sessions.

Until Playground Games releases a proper optimization patch, community fixes are still doing most of the heavy lifting.

My Current Stable Setup

After dozens of crashes and way too much troubleshooting, this is the setup that finally gave me stable gameplay:

Since switching to this setup, I’ve been able to play for several hours without seeing the dreaded Low Video Memory popup.

Final Thoughts

Right now, Forza Horizon 6 feels like one of the best racing games ruined by inconsistent PC optimization. The actual driving experience is fantastic, the world looks incredible, and the weather tech is genuinely impressive. But the VRAM issues are impossible to ignore.

The good news is that most crashes can be reduced with the right setup tweaks.

The bad news is that this still feels like a temporary workaround rather than a permanent solution.

Hopefully upcoming patches improve DirectX 12 memory cleanup and fix the strange VRAM allocation behavior. Until then, lowering texture quality slightly, cleaning background apps, and limiting FPS honestly makes a bigger difference than throwing more expensive hardware at the problem.
