"Could not decompress shader group with Oodle" Fatal Error Reason?

My packaged game gives this error on some computers, crashes and does not start. what would be the reason?

Full error in crash log;

From what i seen, it happen on latest intel cpu due to their high frequency / bios setting.

Some people have tried running on win 8 compatibility with run as admin, and others modifying the cpu speed with Intel XTA but it might not be the best solution to recommend your clients to modify their bios especially cpu clock if something wrongly set.

It also seem to happen on specific map or specific textures on other games.

Hi’ya! I’m running an I9 intel CPU, and this error is popping up, is there a kind of fix you’d recommend?

If you are using the latest intel series, and using manufacture motherboard like ASUS, they have rank up the cpu frequency(even on default), so you will need to set your cpu frequency to Intel Baseline in your bios.

Hi, i got same problem with new subnautica 2. But i have i5 9400f) how i can fix it? i`m aint boost my CPU

Same here with Subnautica 2 and am running a i5-14600K at 3.50Ghz with 32Gb RAM. I’ve updated my Nvidia drivers for my RTX 4700 and tried all of the Window and game tweaks and fixes suggested short of updating the bios and none have worked. I have a bunch of games that all work, it is just Subnautica 2 that doesn’t. I’ve read that this is a known problem for some 14 & 15 gen CPUs but I don’t want to risk updating the bios and it somehow go wrong and I lose the C: drive.

Guess I wait to see if someone rolls out a fix :frowning:

I strongly recommend to update your bios since those crashes can actually damage your cpu as written here: Intel Processor Instability Causing Oodle Decompression Failures

Just follow your manufacture motherboard instruction on how to update your bios cpu.

*It could also be a bug that the dev need to fix since other user like TEMCHIK56 reported the same issue on an intel 9th gen.

There also the solution to underclock your cpu using XTU but i don’t think that worth it for only 1 game.

i also hgave this issue with sub 2 im on a i7 14th gen i think with a 4060 fresh bios update and drivers update with this issue still
