Some people claim to notice extra lag when using a wireless controller, while other people claim that the 4-8 milliseconds of lag is negligible. For wireless controllers, opinions vary as to the effect of this lag. Intel graphics chips, however, should be fine regardless, but it is still advisable to update drivers.įor wired controllers, this lag is negligible. It is advisable to get the latest driver to improve performance, as notable graphics chip manufacturers (e.g.

This can be avoided by using KMS and DRM/EGL, specifically on Linux using these, the user is in control of front and back buffers and don't have to rely on APIs, so that they can find where and when a frame was dropped and how to act accordingly with that in mind. Hard syncing option in some emulators can reduce or remove this.

This applies to both GLX X11 drivers and Windows GL/D3D drivers - both are full of bad hacks and codepaths that cater to benchmarking apps and games. It is a total black box and they do all sorts of crazy buffering schemes under the hood for all sorts of purposes - better scores with benchmarking tests, better 'game' results - but it is actually counterproductive when your aim is low-latency audio/video synchronization for emulators - you don't want all this stuff going on in the background. There is video latency caused by the GL drivers in Windows/Linux. On Windows 10 there is no way to disable Aero. If you're using Windows Vista/7, having Aero enabled will add a noticeable amount of input lag in windowed mode because it forces vertical synchronization at the OS-level. Once the frame has been processed, the final step is the pixel response time for the pixel to display the correct colour for the new frame.ĬRT TVs (Standard Definition models) and monitors have no discernible display lag. Discussions on gaming forums tend to agree with this value.

It is generally considered that input lag of a television below 30ms is not noticeable. Image processing (such as upscaling, 100 Hz, motion smoothing, edge smoothing) takes time and therefore adds some degree of input lag. This is the lag caused by the digital televisions and monitors.
