above are the kernel parameters that solve the tearing issue
modprobe.blacklist=nouveau -> blacklist nouveau from loading if installed
i915.enable_psr=0 -> Panel Self Refresh (PSR) enabled by default since kernel mainline 4.6. To disable this feature use the option i915.enable_psr=0 [6]
nvidia-drm.modeset=1 -> this is for PRIME Sync [5]

Reference :

[2] : Bug 1573482 - i915.enable_rc6=0 is not respected in new kernels
[3] : What are CPU "C-states" and how to disable them if needed?
[4] : Kaby Lake is unleashed with Linux kernel 4.10 | PCWorld
[5] : Vulkan not working if nvidia-drm.modeset=1 is set and gdm3 is used (Optimus)
