Will I notice the diff between 240 and 300hz?

So I preordered a ASUS laptop with a 300hz 3 ms panel. I guess due to coronavirus it has been delayed and there is no word when it will come out.

There is another laptop I am looking at with a 240hz 5 ms panel. I was really excited to have a 300 hz screen because of how ridiculous it is, I am just curious if there is any real difference I would see?

Thanks!

I have a Razer 240 Hz IPS laptop here, a Blade 15 is the workhorse laptop for my convention travels, but it has been my backyard laptop for now when I have cabin fever. (The covid situation)

From what I saw of 300Hz, the difference is visible but very slight.

The rule of thumb is geometric refresh rate upgrades (such as doubling Hz, 120Hz to 249Hz to 480Hz to 960Hz), with preferably at least 1.5x refresh rate upgrade for desktop sized monitors. At only 240Hz vs 300Hz, the difference is so slight on the smaller screens of laptops, the 3ms GtG vs 5ms GtG is a more human visible difference (5ms realword translates to 5 pixel of artifact per 1000 pixels second)

Browser scrolling benefits (flick scroll via touchpad) is quite noticeably better than a 120Hz iPad, as double Hz approximately halves display motion blur (Subject to GtG limitations bottlenecking Hz-improvement benefits), but only faintly noticeable between 240Hz and 300Hz, due to need of geometric Hz differences. For gaming, it’s harder to notice, and becomes unnoticeable when the GPU struggles to reach 300fps.

You will certainly get enough frame rate to see 240Hz benefits in many very old games (Source engine, older Bioshock, etc) with the RTX chips and 230-watt laptop power bricks like these laptops now include, in my experience (hoo boy, laptop are space heaters, get a small tray or piece of wood whenever gaming on your lap)

That said, frequent struggles (150fps-300fps) will muddy the benefits of 240Hz to 300Hz, even if things are quite noticeably better than 60Hz.

My current laptop is 75 hz and I have been overclocking it to 100hz for 3 years.

I am wondering how high I can OC a 240 hz panel. Probably 250hz at the least.

My experience is that overclock headroom of the Razer is extremely small. Not sure how much ASUS can overclock. I would stick to factory Hz on these particular panels, but you can test for surprise headroom.
