Performance without borders or exclusive full-screen playback
Performance without borders or exclusive full-screen playback
Hello everyone, I've noticed that certain games use full-screen mode without any restrictions, while others offer complete control over screen settings. Are there noticeable performance variations between these two approaches? Some titles even lack an option for exclusive fullscreen in their graphics settings. I've seen many videos on YouTube trying to explain this, but I haven't found a clear answer yet.
In full screen mode, the GPU handles just the game, boosting performance, but when you close it, it returns to the background faster—sometimes showing a black screen for a short time. This is faster than windowed or borderless setups that load both the game and your desktop, which slightly reduces speed but allows smoother transitions between applications.
It was mentioned that the issue stems from the DirectX12 API, which doesn't offer full-screen support by default. This limitation is only present in games where developers manually enable exclusive full-screen mode.
In theory, full-screen or exclusive full-screen would work better, but in practice windows aren't always that way. That means they don't have to deal with v-sync and AA as much as regular desktop does, though usually at a low resolution.
Technically exclusive fullscreen offers performance advantages, but Windows 10 and 11 no longer support it. Applications using it operate in an emulated exclusive fullscreen mode. In reality, this is essentially a borderless window running under the hood, eliminating any real performance gains. Borderless Window, on the other hand, functions like a standard application window without borders, appearing identical to fullscreen. It provides faster transitions between apps, avoiding the lag associated with switching from emulated fullscreen to the desktop.
Currently there are no deals with "exclusive fullscreen" availability. It's been unavailable for a while now.
Windows 11 offers identical performance and latency results compared to other versions. The borderless windowed mode leverages hardware-independent flipping, giving the GPU full control over the display just like in exclusive full-screen modes. There’s an option to enable borderless window optimizations, which reduces hardware strain during DSC games. The background rendering of the desktop remains extremely efficient, making it a great solution for bypassing DSC handshake problems.
Thanks for sharing your thoughts. It's clear you're curious about how .ini files affect game settings. In some games, you can enable exclusive fullscreen mode even if it wasn't included in the original graphics options. As someone who enjoys playing classically, you might wonder whether you need to change anything or just stick with the current setup.
