Updates in Graphics and Gaming

Introduction 

Optimization is everything within gaming. Whether it is tuning your display, choosing the perfect mouse and keyboard, or tweaking game settings to your preference – the goal is the same. We all want the best gaming experience possible. We understand that you want to see the best out of your games and your PC, which is why we are excited today to introduce you to Optimizations for windowed games. This feature has the ability to significantly improve latency and unlock other exciting gaming features including Auto HDR and Variable Refresh Rate (VRR). Latency improvements can benefit all gamers – from improving your input lag to creating a competitive edge in your gaming experience. Keep reading to see what we’ve added and how you can benefit. 

Optimizations for windowed games 

You might be asking, “what are optimizations for windowed games”? Great question! Let me explain – this setting affects presentation modes used in Windowed and Borderless Windowed DX10/DX11 games. Presentation is the method for getting your game’s rendered frames on your display in the most optimal way. To learn more about Windowed and Borderless-Windowed, check out the Appendix. 

 This new optimization specifically applies to Windowed and Borderless-Windowed games because when you’re running in Fullscreen, a similar optimization already exists, and this new setting brings a consistent experience no matter which mode you are running in. You don’t need to worry about DX12 games as they already take advantage of the new presentation mode. Specifically, this optimization works by upgrading the legacy presentation model used by a game to a modern one. If you’re wondering more about the various models and how they impact performance, check out our dev blog here which dives deeper.  More technically, we are moving apps from the legacy blt-model presentation to modern flip-model. Many games already take advantage of modern flip-model, but this new optimization will allow thousands of games to benefit as well.  

But we called this an optimization, so it does more than just unlock stellar gaming features. Flip model generally results in lower latency.  Reducing latency means getting your game’s frames to the screen as fast as possible.  

 When your game is configured to not use v-sync, this can result in a new frame being ready before the previous frame is displayed. At high frame rates, this may lead to screen tearing when this feature is turned on. To avoid tearing in your game, you can make sure to configure the game’s frame rate to match your monitor’s display refresh rate. Another option is to turn on v-sync in your game, which is often found in the game’s settings. If neither of those options work for your gaming experience, you can opt out of this feature and the instructions on how to do that are explained below. Another way to address tearing is by using a VRR monitor which can take advantage of the lower latency. However, please note tearing is still possible if you exceed the refresh rate of the monitor.

The Best Settings by Default 

We strive to deliver the best graphics settings in your games by default. Some of the options in Default graphics settings may be checked by default because the app is not compatible with the setting. You may also see a warning message if you uncheck the option. This means that the app may crash or there is an issue with how the feature interacts with the title. In short, we disable apps that have known issues on default to ensure that you have the best settings without having to do much guesswork on what might be wrong.

Appendix

Windowed and Borderless-Windowed Gaming 

Windowed gaming is what it sounds like. Instead of taking over your entire display, the game is put into a Window that can be moved around and resized depending on what you want. In a windowed format, other things can be displayed on top of the game. Examples include the Game Bar, overlays and notifications. Windowed gaming can be beneficial as it makes it easy to switch to other windows or applications.  

Borderless-Windowed is very similar to windowed gaming as it runs the game or application in a window except the window is typically at a full screen size and without a border. This creates the experience of full screen while also allowing for other overlays on top of the game, similarly to the windowed gaming experience.
