Are you sure this is caused by entering water in particular? Doesn't the same thing happen if you fly up and down above water (between Y=70 and Y=75 for example)?

[quentin452]

you mean do I have the same problem between Y=70 and Y=75 without going into the water?

[makamys]

Yeah.

[quentin452]

no i don't have the issue

[quentin452]

I just have 100 - 200 fps difference

[quentin452]

the water in my test Y=62

[makamys]

What about when moving between Y=75 and Y=85? I'm thinking it could be about traversing a subchunk boundary (such as Y=64 and Y=80).

[quentin452]

i will try between 75 and 85

[quentin452]

no issue

[makamys]

Hm. I guess it really is about water then. I'm going to say this is low priority though, since you still get about the same amount of FPS (1800) with ArchaicFix in the worst case as without it.

[quentin452]

yes , i know 1800 fps is alot :D

[quentin452]

i tried when i go in the water, instead of looking ahead i look at the sky and there is stuttering

when i test between y level 75 and 85 i don't stutter

it really is a water problem

[makamys]

Actually I'm not sure if it's really caused by crossing the water's surface. I just tested and I get \~180 fps flying up and down above water (y=64\~67), \~170 fps if I'm crossing its surface (y=59\~63) and \~160 fps if I stay underwater (y=55\~59). This is when I'm looking forward. If I'm looking upwards, it's \~220, \~200, and \~190 fps respectively. So my fps drops while I'm underwater, not when I go underwater.

Threaded chunk updating & the occlusion tweak were removed from ArchaicFix in 0.7.0, so this issue is no longer relevant.
