Open them full screen, look at the building right behind the observation deck of the ATC Tower and the buildings in the distance on the far left of the airport

It’s subtle, 200 is better quality/detail, but the difference is there! Once you see it you cant unsee it lol

Edit: It’s definitely diminishing returns above 100 though

@TheOriginalBabu

Under a CPU bottlenecked scenario,
10 at 70 FPS
100 at 63 FPS (11% reduction)
200 at 60 FPS (17% reduction)

Under a GPU bottlenecked scenario,
10 at 24.2 FPS
100 at 24.1 FPS (0.5% reduction)
200 at 23.4 FPS (3% reduction)

Edit Edit: The OP says he is going to retest this with SUXI! Watch this space
