I also experience this since long and I made a topic about it here with a temporary solution: https://codecs.forumotion.net/t3747-stutter-while-playing-videos-solution-please-add-the-option-to-enable-v-sync-to-mpc-video-renderer-or-if-possible-to-madvr-as-well
Force V-Sync on MPC in Nvidia control Panel. I just hope the V-Sync option can be turned on within the player on madVR or the MPC Video Renderer which is now the default one.
IMO the dev should enable VSync by default on these renderers.

Based on the report, I see you use are using the EVR CP renderer, this should allow the VSync option to be turned on within MPC. Just go to View > Options > Renderer Settings and turn VSync on, this should solve the stuttering. If it doesn't, just use madVR or MPC Video Renderer and force VSync from the Nvidia Control Panel using the "Program Settings" in "Manage 3D settings" and apply it on MPC.

Not sure why it's grayed out, maybe depends on hardware after all. Anyway I think I can sometimes feel a bit of stuttering even with VSync on but it's at least 90% better than before turning VSync on.

I found the best setting is using madVR and setting "frames to present in advance" to 2 (setting it to 1 can cause screen tearing) in madVR settings (as suggested by Admin in my linked topic) and turning on VSync in Nvida CP. You can also try MPC Video Renderer with Vsync on in NCP.

How much stuttering you have depends also on your monitor, not just the GPU. I have a Full HD 24" normal monitor with zero stuttering even when VSync is off but on my 43" 4K it's the worst.
