Endgame Gear OP1 8k vs OP1 8k v2

Hello everyone, the OP1 8K has better Sensor latency values than the OP1 8K v2 (at 8k Hz Polling rate): Delay To Start Of Movement: 8.8 ms vs 9.7 ms

Delay At Half Movement: 1.1 ms vs 1.0 ms

Delay To End Of Movement: 0.3 ms vs 0.5 ms. This makes me not sure about which mouse I should get. The v2 weighs a little less. But they are both so extremely light anyway that I think the better sensor would make the difference. And according to your testing of the sensor performance the 8k sensor (PixArt PAW3395) is performing better than the 8k v2 sensor (PixArt PAW3950). How do you assess the test results and my corresponding question? Best regards

Hey! Thanks for reaching out.

We’re at an interesting moment for gaming mice right now. Performance is increasingly approaching a theoretical “perfect” threshold. At this point, our editorial position is that we strongly recommend people avoid making buying decisions based on small performance differences between mice. Instead, it generally makes more sense to focus on other factors like shape and build quality, or more practical considerations such as warranty support, expected component longevity, or weight, if that’s particularly important to you.

Our testing didn’t find any meaningful difference between the original Endgame Gear OP1 8K and the OP1 8K V2. While our sensor latency measurements on the V2 came in slightly higher, we don’t think it would be accurate to say that the mouse performs worse as a result. It’s also important to note that our testing has small margins of error, which can account for differences of this size. From an extremely practical standpoint, this degree of difference is functionally nonexistent and far too small to ever be noticeable in game.

It’s also fairly typical for newer hardware to initially trail slightly behind older hardware that’s had more time for firmware iteration and tuning, and we’ve seen this cycle play out several times. It’s entirely possible that if we were to retest this mouse six months or a year from now, it could perform slightly better on our test bench. That said, the 3950 is only a minor revision of the 3395, so we don’t have much expectation of a major performance uplift regardless.

All of that is to say, we’d strongly encourage you not to focus on performance differences between the two when making your buying decision. If you can find a V1 version at a good price, we still think that’s a very compelling option, and the bump in price for the newer version may not be worth it depending on your priorities.

On a more personal note, the change to a new dustproof encoder on the V2 is the update I’m most interested in. That alone would likely justify choosing the newer version for me, as we’ve seen more reports than we’d like of early scroll wheel encoder failures on the V1. That said, I personally own a V1 Endgame Gear XM2 8K that uses some of Endgame Gear’s older-sourced encoders, and it’s held up extremely well despite heavy use, so this is more of a precautionary suggestion than anything.

I hope that’s helped to answer your question. Best wishes!
