I tested my reaction time via https://humanbenchmark.com/ and noticed that I've improved by about 24 ms over 8 years

As much as I want to believe that my brain somehow improved as I got older (age 20 vs age 28), I think it comes down to an improvement in overall system latency.

Current (2023) system:

• Mouse: Logitech G Pro X Superlight
• Monitor: AOC Gaming 24G2ZU @ 240 Hz
• CPU: AMD Ryzen 5 5600X
• GPU: Nvidia GeForce RTX 3070
• Browser: Google Chrome

2015 system:

• Mouse: Logitech G400S
• Monitor: Samsung SyncMaster P2450H @ 75 Hz
• CPU: Intel Core i5-3570K
• GPU: AMD Radeon HD 7950
• Browser: Google Chrome

Each row entry below is a sample size of 5 runs, averaged. So 20 tests for 2015, and another 20 tests for 2023.



I'm not sure if 24 ms is a notable enough difference to draw any conclusions, though I did find it interesting. It's also worth noting that during 2015 I had persistent mental health issues that could have worsened my reaction speed as well. Has anyone else logged old reaction time benchmarks on that website? How do your results compare to now? I'm very interested to see if anyone else has noticed a similar phenomenon

In 2023 browsers already use hardware acceleration.

Lower your refreshrate on your AOC Gaming 24G2ZU and retest, I'm thinking 75hz vs 240hz.

Most browsers, Chrome compositing, combined with Windows compositing, tends to have 2 or 3 refresh cycles of latency.

There's a major latency difference with refresh rates.

2 refresh difference = ((2/75) - (2/240)) = 18.3ms difference
3 refresh difference = ((3/75) - (3/240)) = 27.5ms difference

It is probable that a percentage of the difference will be the refresh rate difference (aka lower system latency).

Keep in mind that 75Hz-mode on a 240Hz panel, usually has more lag than 75Hz-mode on a 75Hz panel. Check RTINGS to see if their 60Hz-mode is low lag (e.g. XG2431).

This is attributed to differences in how higher-Hz monitors handle lower fixed-Hz non-VRR refresh rates.
