Play the game at native 4K without stutter and slowdown.
How to Play at 4K Without Stutter and Slowdown
- Select Borderless Fullscreen mode.
- Change the resolution to something below 4K, but keep resolution scale at 100%.
First off, the borderless mode in this game makes use of DXGI Flip Model, meaning that there should be no latency or performance penalty for using it instead of exclusive fullscreen. Nothing is being compromised from a competitive perspective.
When in Borderless Fullscreen mode, the resolution option in-game doesn’t affect the rendering resolution of 3D elements on screen, but it does affect the rendering resolution of the HUD. This is easily confirmable by dropping the resolution setting to an extremely low value and loading up a game. By dropping the resolution of the HUD to 1440p or 1080p, it 100% fixes the stutter and slowdown on counter hits and other affected game states.
