Windows Vista SP1 Compatibility Mode

[Schoolofmonkey]

Why do we with a 13900k/4090 have to run this game in Windows Vista SP1 Compatibility Mode, it's odd.
Can't get past the first loading screen, but once you turn on compatibility mode it's fine.

So it can't be unstable hardware related, seeing the same said hardware can run Alan Wake 2 fully max out for hours with no crashes.

What in the blue blazers have they put in the game code that's looking for a f: drive when compatibility mode isn't on. (I don't have a f: drive btw)

This looks like a different error to the one i have seen others experience. Have you tried changing the Window settings, start the game up and in the video settings change it from Fullscreen to Windowed Fullscreen.

I've worked it out, it's the exact problem Lords of the fallen and Slenderman remake had, I underclocked my CPU to 4.9Ghz and it worked fine without compatibility mode.
(This was from stock Intel settings BTW)

It took 3 patches for the LOTF devs to fix this shader caching issue on the 13900k.
Just have to wait for a patch or downclock the snot out of your 13900/14900k's....

RTX 4090 24GB
Windows 10

The game started up fine and I played it for almost 3 hours. I didn't need to mess with any compatibility settings. I did install the latest NVIDIA driver right before turning the game on for the first time. The only issue I noticed was hitching here and there while walking around the city and slow texture loading. I think this game would be best installed on an SSD or NVMe. I have it installed on an HDD. My next build will be all SSD now that they are bigger and cheaper.

I noticed there seems to be a lot of people having issues with recent games that own the 19-13900K. I hope I don't have that issue because that is the CPU I'm going to get for my next build soon. I intend to not use X.M.P. on the RAM, no overclocking on anything and adjust the CPU PL 1 and PL 2 power limits to Intel's recommended settings. Many motherboards have their BIOS set to crazy high numbers by default making this CPU use more power and generate more heat than necessary. I had to disable X.M.P. on my RAM to make some games stop crashing. I'll never enable that crap again.

I don't know why you are having this issue. The game is running pretty good for me.

edit: It took me too long to type this. You already found a fix. lol

Just a followup, if any core boosts above 5.2Ghz you'll get a LowLevelFatalError crash.
I've been manually boosting core, it will instantly crash with Intel default/power limits enforced, but if you start setting hard core limits, currently 5.2Ghz on 3 cores, 5.1Ghz on all 8 core, the game is happy.
Any higher deviation from that, it'll crash, EXACTLY like Lords of the Fallen pre 4th patch..
It's a Unreal Engine problem that has to be sorted out by the devs..

You DO NOT have to do anything of this when using Windows Vista SP1 compatibility mode..

On the first load the game will compile all the shaders, right at a start, before even the main menu shows up. There might be some instability with your hardware/overclock. On my k-less 12700 Robocop took about 2 minutes or less to finish compiling shaders, while menu were at around 20 fps, CPU was at 100% load all cores during this time.

Nah mate, my system is 100% stable, it's only the Unreal Engine 5 games that do it, once Lords of the Fallen was patched properly the crashing during shader compiling stopped.

I just synced all cores to 5.7Ghz as a test, still loaded with all my normal voltages, so it seems it likes a locked in core clock, not a fluctuating one (core clock on specific load).
It's really only the 13th gen (maybe 14th) that continues to have UE 5 issues which are fixed with patches once the devs fine what the problem actually is.

See what backs that up is the game not crashing in compatibility mode.

How do you do that ?

[Moderator Abuse]

Shader issues all over the place on Google Reddit has numerous fixes and underclocking the CPU multiplier is common.

Yeah just how the hell you do it pls ?

It works, thanks, no need any compatibility ♥♥♥♥♥♥♥♥ anymore. Just nee to Install Intel ETU and reduce Core CPU Ratio to <5ghz. THANKS bro ... 2 days I'm checking everywhere, even their support couldn't tell.
