Lost Planet 2 "Black Screen after launcher" fix for AMD Ryzen users

[Weeble Wobble]

I'll be brief.

Install the AMD Ryzen Master which is Ryzen's overclocking utility https://www.amd.com/en/technologies/ryzen-master

From within Ryzen Master, go to a new profile and turn on "Legacy Compatibility mode".
Save the profile, hit "Apply" at the top which reboots your computer.
When you reboot, you should be able to run the game.
If it still doesn't work, try disabling some more cores manually.

I would not recommend leaving it in compatibility mode after you're done playing, because it looks like it cuts down the number of cores your system utilizes in half.

Bear in mind that this fix was applied AFTER I tried all of the GFWL fixes, so maybe it's a combination of things that got me up and running.

Good luck!

Thank you very mucho! Worked for me

6 cores max:

Stupid multiple DRM system with checksum on exe files won't allow users to patch the exe manually with ImageCfg[robpol86.com] unfortunately (once and for all, and no need of BIOS or Ryzen Master changes).

I think this should be reported to AMD, maybe they can do something adding this game to a old compatiblity mode blacklist.

...or you may try with MS Application Compatibility Toolkit:
https://docs.microsoft.com/en-us/windows-hardware/get-started/adk-install
And try shims like "EmulateSlowCPU" and "ProcessorCountLie" etc.

I don't have AMD cpu with 8+ cores so I can't test and find the solution myself.

I know it has been a while but what parameter would I use for the "ProcessorCountLie" shim?

I tried simple core numbers (1,2,3,4, etc...) and hex values like the affinity parameter in the task manager but they don't seem to have any effect.

I'm giving up. I tried Ryzen Master and bios disabling cores and it doesn't work. The game is a pita to install but once going, it worked perfectly fine on my old 6700K. I like play LP2 a lot and it's a shame it has not worked with my Ryzen 8-core. I'm going to switch to a Ryzen six core. I'm waiting for the final numbers on the 5600X (vs the 3600X), and then sell my 2700X

Unfortunatey the EXE has also a checksum which prevents for example ImageCfg tool to patch it permanently for 6 cores max, probably due to anti-cheat in multiplayer

Shot in the dark, did you try the gfwl stuff?

I picked up Ryzen 3600XT from Micro Center and the game launches now. Selling my 2700X.

Fought for three hours getting GFWL to work. Non of the guides worked. Finally, found something on MS/Xbox support forum; sign into your windows account through windows!!! I forgot to do this and it worked with a clean install (including the og GFWL installers). A few updates later and it's now working. Funny, I got an offer and I'm off to sell the Ryzen 2700X :p

Nice.

It's incredible... a game that refuses to work with 7+ cores, bah...
We need an official patch at least to unlock this stupid check.

Let's try through CAPCOM support:

Please, let's all send them a mail reporting the issue with Lost Planet 2. I've sent mine.

Not sure if it's due to my Ryzen being a dual CCX. Maybe the new Zen3 bassed chips will be able to work better? Maybe not....??? Anyways, I appreciate the extra core speed I have and boosts are also up. I seriously forgot about the XT, and found it when shopping for the 3600/3600X. For an extra $20, I rather have the extra speed out of the box. I already crashed my system hard trying to get my Corsairs to 3600 (left them at stock 2933...or what ever it is).

I had to step away and didn't get a chance to game. Though I'm super relieved it's now all works as it did with my old intel Skylake setup.
