Re: Adaptive vsync vs Regular vsync Nvidia driver

I also feel that "Adaptive VSYNC" has smaller input lag that regular VSYNC. I think that it is using double buffered VSYNC and thus has lower input lag versus the classic VSYNC which usyes 3 buffers. Are there any input lag tests for this? Normal v-sync is double buffered, and has the same input la...

Re: Input Lag Test Analysis with Arduino Due and a 60Hz moni

However I notice there is quite a lot of variance for each run of the test (each line) initial climb start time when using random delays between each test. If i set the delay between each test to the same e.g. 1000ms, then the graphs line up almost perfectly (initial climb start the same time each ...

Re: Measuring keyboard input lag

The three approaches I think are best all have in common a test platform capable of both GPIO and USBHost. 1: Mechanical input to USB output. Attach an accelerometer or contact microphone to a mechanism that can press keys with good repeatability. measure the time between when the mechanism touches ...

Re: Is this normal ?

The framerate meters you have are implemented before the GPU, so they won't show you fluctuation in frame time caused by different frames taking different amounts of time to render.

Re: USB Latency Tester using Light Sensor

Well, that patent date is after the leo bodnar tester came out, and mostly seems to deal with touchscreens. Is there a specific part of it that you're worried about? There are also a couple implementations similar to your device on this forum: https://forums.blurbusters.com/viewtopic.php?f=10&t=3005...

Re: 2 monitors side by side input lag test help please

The difference in input lag between the two monitors doesn't change with framerate, you'll just be able to see it more consistently. Say you have two monitors at 60hz, and the timer is running at 30fps. Depending on when the frame completes, a monitor will be displaying the image for 33ms, or it mig...

Re: 2 monitors side by side input lag test help please

The timer you're using might have a very low framerate when compared to the refresh rate of the monitors.

Re: 2 monitors side by side input lag test help please

This type of test needs to be run many times. The refresh rate of the monitors and framerate of the timer have a big impact, so you need a lot of samples to figure out exactly how big the difference is. Keep taking photos until you get several where the number on both monitors is different, the prop...
