Filter Mode :Point,Bilinear,Trilinear. which is the cheapest?

or Does Filter Mode Has something to do with performance?

 

Point is cheapest. Then bilinear, then trilinear.
Just experiment with small texture and you will see.

 

Thank you.

And I will post my test here later.

 

Still waiting bro... it's been 5 years

 

Okay, since the OP probably isn't going to provide test results, I am going to give it a shot:

Screenshot of same icon at different resolutions with different filter modes and mipmap states.
[Default icon resolution is 512 x 512 but I only went up to 256 x 256.]​

Disclaimer: I have not explored the many options/settings (available with version 2017.3.0f3) like aniso level and different compression qualities. As such, I only have provided various filter mode and mipmap states.

So, I came across this thread and a related Reddit post (ultimately about mipmaps) after attempting to figure out why my canvas images made my sprites look blurry (before and during runtime). Immediately after, I assumed that filter modes and mipmap states would result in uniform results - regardless of size. Apparently, this is not the case; It turned out that I needed to use different filter modes along with enabling/disabling mipmaps (depending on icon size in-game).

As you can see from the screenshot above, and I encourage viewing at full res for better understanding, trilinear filtering seems to provide the best results (as expected). However, not using mipmaps closer to native resolution seems to provide better results than it does at lower resolutions. This is not my area of expertise, but I hope that this will help those who are also looking to create clear 4.6 UI images within a canvas.

 

Thank you for taking the time to create the comparisons.

 

No problem! As an added bonus, for the year anniversary of that post (nearly), experimenting with the PPU (Pixels Per Unit) in the import settings may be required for certain sprites, icons, and 9-slice images. This is especially true when with 9-slices that are meant to replace the default UGUI "UISprite" background of buttons and toggle backgrounds. As always, I hope this helps anyone who might need it.

 

Thanks @JackofTraes for that comparisons chart . But can someone help me toh know how they impact the performance of the game , like for mobile games ?

 

Lol
