Hi,

I don't play minecraft much but my 7 year old son does. I recently put together a new PC and the graphics on the game when it starts seems odd.

I've attached a screenshot (where you can see wavy lines in the distance on the water).. when over land, there are still similar issues.

Has anyone encountered this before. It was just installed and there are no mods.

I have:

Intel i7-6700K

EVGA 980ti

Asus Z170-delux

Gskil ram - 16GB

Samsung 950pro 512GB (game installed on this)

Western Digital 3TB HDD

I went into the video settings in minecraft and selected the same settings as I had on my old PC.. still no luck...

Please let me know if anyone knows whats going on?

(FYI: I notice that the fan on my GPU is not spinning when the game runs.. it does spin when I play other games, but perhaps the GPU is not being used much to get hot enough for it to call for the fans to spin)...

Are all of the drivers installed?

If so you should probably dedicate more RAM to Minecraft. It's easy, just go here: http://www.wikihow.com/Allocate-More-RAM-to-Minecraft

I think I had the same problem and when I re-installed all of the drivers and allocated more RAM (Normally, it's 512mb but I set It to 3gb)

I hope this helps

These are called Moire patterns and can be seen anytime you look through two overlapping grids (like 2 screen windows, or a computer display + a grid based graphics image)

Thanks everyone for the info.

I've increased the ram assigned at launch to 4GB from preset of 1GB (figure it can't hurt).

I do know what Moire patterns are.. The issue I'm facing is that on my old PC, I see no indication this is happening, on my new PC it's just an extreme amount to the point that it is very distracting..

Given both PC's are connected to the same monitor, I would have to think it has something to do with my drivers (which are all updated), or something else I'm overlooking.

Maybe I'll try reinstalling minecraft to see if that does anything...

I wish I know how to post a short video so you could all see it. I think if you saw it in action, you would all say something isn't right....

installing a high resolution resource pack could possibly smooth that out some

is the output resolution of your two computers the same?

The other thing is that this effect is increased (to the point of causing 'purple water') if your GPU's AA/AF settings are less than optimal for Minecraft.

This is because the 'griddiness' of the MC world can be exaggerated if the textures on adjacent blocks don't slightly meet/overlap.

Thanks everyone for your input.

gerbil, I took your advice.

I checked line by line the settings in my Nvidia control panel.

On my old PC, the Anisotropic Filtering was set to application-controlled

on my new PC, the settings defaulted to 8x.. Once I changed this to match my old PC, the game looks normal again...

the waviness is normal, its a form of optical illusion from repeating patterns, not much can be done about it

I've had that issue before, it's a mishap with anisotropy. I had the same issue with my 980's and fixed it by disabling anisotropy from the Nvidia control panel. The difference between this and your usual moire patterns from aliasing is these patterns appear at the edges of blocks. This issue is made worse by mipmapping, whereas usual moire patterns are somewhat fixed with mipmapping. Anisotropy is also supposed to fix this issue, but for some reason Minecraft doesn't like it to be forced on.
