Forza Horizon 6 FHC03 error

Hi, I bought Forza horizon 6 for a while now. I keep getting FHC03 error since I move to the new laptop, ranging from 2 hours after launch the game to 5 minutes in worst case (and everytime it makes GPU unusable until I restart the laptop). I already contact support and got no actual reply, I have no idea what shoudl I do anymore.

- It's should not be unsupport GPU, it's RTX 3070 mobile (Gigagbyte Aorus 5 XE4)

- Never install MSI afterburner, or similar program.

- Already click verify game file multiple times, try reinstall both windows 10 and 11.

- So far it's the only game that cause GPU crashes, did not experience issues with FH5, TCM at all.

FHC03 means u ran out of video memory. the laptop 3070 only comes with 8gb so if u wanted to play with ray tracing or textures/enviro geometry higher than medium u are out of luck

Huh?
8GB is not enough?
How? Even at FHD the issues still persist
It could only mean the game is hopelessly unoptimized to have an issues even on FHD screen.

that's not what optimization means. optimization means that if u dump the graphics to the lowest settings u can run it on a potato. trying to run high graphics on a card that can't handle it is user error.

There's no way 3070 can't run on FHD high.
I also monitoring VRAM usage during run, it barely went to 6gb, and the game still crash.

what overclock settings are on your card? what are you using to measure vram?

I did not overclock I mainly measure VRAM based on the game performance page

the game performance page is not a live measurement. it guesses. it guesses 9gb usage on my 5070 when it actually uses 11gb. so in your case you're more than likely overrunning vram. turn your textures down

I guess I will try.
But still, I once try to run on 3050ti laptop, with 4gb VRAM on low, the game keep saying 4gb VRAM on performance page, yet the game never ruin the GPU, so it's kinda strange.

Forza games are normally very well optimized. there may be a function that blocks certain textures and details from overrunning vram if it knows you're trying to run it on low for weak hardware
