Rockstar Games has released RDR2 update 1.14 for PC and consoles which addresses the apparent stalls on 4-core and 6-core CPUs.

The PC version of Red Dead Redemption 2 was released last month, but since its launch, players have been plagued by stalling issues. Those using 4-core and 6-core CPU were required to disable some cores in order to be able to play the game properly. Luckily, this new update should resolve these issues. Rockstar notes that players using an NVIDIA GPU and a 4-core or 6-core CPU should update to GeForce Hotfix Driver Version 441.34 to fix the issues.
