The funny and weird part is that 2K and 4K are popular gaming resolutions, and I find it odd for the company to not include these under the default preset option. Instead they included 8K options, which is pretty much useless for most gaming PCs, at least for the average PC user.
Although, the 1080p Extreme option is '4K Optimized' as the company claims, for high-end gaming PCs, but this has not been mentioned clearly as well. Confusing to say the least.
I just tried the 8K preset and it almost fried my PC, lol !
