I didn't see this game listed in the compatibility liist..
Lord of the Rings, The - War in the North [BLUS-30421]

Played for about an hour, never had any issues. I even bumped the resolution up 150% and it still ran like butter.
Other GPU settings I tweaked:

Output scaling option "FideliityFW Super Resolution"
RCAS Sharp set to "100"
Multi-thread RSX "on"
Async Texture Streaming "On"

Title is wrong. GameID should be "BLUS30421" not "BLUS-30421" (no hyphen).
Game Title is wrong. Should be "The Lord of the Rings: War in the North" not "Lord of the Rings, The - War in the North".
Just right-click the game in RPCS3, and go Copy Info > Copy name and serial. Then use that as the title, its far easier.

I fixed it for you.
