By default, minecraft only allows the use of 16x16 texture packs by default. this means that there are basically 16x16 squares per side of block and they each have their own color. Some of these packs look pretty decent, but obviously the lower the total amount of squares per side the less "good" you can make a block look.
Thats where higher res texture packs come in, such as 32x32 or 64x64. These are a bit harder on the computer but anything up to 64x64 should be easy for it.
For our demonstration we're going to use the albion texture pack
Heres an example of what it looks like
Step 1 (for old launcher): doing a clean install of minecraft
backup any saves you want to keep and then delete your entire minecraft folder (found in the hidden file appdata) except for the actual minecraft client
run the minecraft client (this will re-dl everything)
close minecraft
if the new launcher works for you, then you should just get that and do the alternative step 1 (go to the official site and download minecraft for newest launcher)
Step 1 (for new launcher):
- this is the new launcher:
click Force Update in the options of the launcher and then login
Step 2: get the texture pack and the high res patcher
actual texture packChoose the right ver for your OS and download it from
hereStep 3: changing the res minecraft texture packs use
open up the texture patcher you downloaded in step 2
change the resolution to 64x64 (if you do this for a different pack, change it to whatever res that pack uses. ex albion uses 64x64 so we set it to 64x64)
patch minecraft
Step 4: final stuff
In the patcher click open minecraft folder location.
Take the albion texture pack (as a zip... do NOT unzip) and place it in your minecraft folder's texture pack folder
start minecraft up again
go to change texture pack, and choose albion
your game should now look 100x better!
