I posted this earlier, but decided this issue is probably common and warrants it's own thread...

I'm having a strange problem with Win10 64-bit that I never experienced with Windows 7 64-bit.

Playing in fullscreen produces a regular stutter no matter what my framerate or vsync setting. I've found that limiting my max pre-rendered frames to 1 in the Nvidia control panel greatly reduces the effects of the stutter, but doesn't completely solve the problem. Turning off "Threaded Optimization" removes the stutter from in-game menus.

This isn't performance related. It isn't dropping frames. Something is out of sync between my GPU and display. The stutter is constant and fast resulting in a sort of blurred stop-motion effect.

The only way to run the game with my GPU and display truly in sync, with no stuttering, is to play in windowed mode.
Unfortunately this mean I'm unable to use DSR, something from which this game's visuals would benefit greatly.

Another problem with this game's windowed mode is that it automatically leaves room for the taskbar and window border. Manually resizing the window in environment.cfg and denying write permissions at a system level doesn't stop the auto-resize function, nor does forcing fullscreen with Borderless Gaming.

The only way for me to play this game with no stutter and (almost) no border is to:

1. Hide the taskbar.
2. Change the desktop wallpaper to solid black.
3. Launch the game in windowed mode through Borderless Gaming.

Borderless Gaming is set to the default "Fullscreen" configuration.

I played around with BG, trying to get the Riddick window to run at full resolution but there just isn't a way to force it. No matter what, the game will resize to leave room for the window border, even when it's removed with BG. This is why I have to set my wallpaper to solid black, because it peeks through the top and bottom of the screen. If anyone has any ideas I'd love to hear them.

I'm running an EVGA GTX 1080SC, DVI-D to a 1080p 60hz monitor.

UPDATE: This issue is 100% because of the in-game Refresh Rate option. 60 apparently does not mean 60. When selecting a resolution for which the game will allow 75hz, Nvidia vsync takes over and the problem is solved. However, Riddick seems to pull the first available refresh rate for any given resolution from your system and it can't be overridden with the environment.cfg file. Forcing Riddick to recognize a refresh rate beyond my monitor's rate (or somehow unlocking Riddick's refresh rate) would solve everything but I'm not sure how to do that. Setting a custom resolution in the Nvidia control panel isn't an option because then my monitor would actually overclock to that refresh rate. Any ideas???

Steelyphil, I was having the same performance problems until I went into Nvidia control panel and disabled Antialiasing - Gamma correction and V-sync.

Hopefully that helps.

idk if you still see this forum, but my problem was that in Nvidia setting, there's an option for power saving at the bottom of 3D setting section. I simply made it full performance and the problem seems to go away after that. If everything else didn't work, I recommend trying that.
