Hi Max, thanks for your reply.
The result is from a desktop environment, I should have been more clear, my bad.
It has little to do with my zoom, it's on 100%, always.
Even without the use of custom shaders, the render result is very jagged and blurry on all of my systems.
Can you, or anyone verify this is the result of this small demo? (see share.zip under 'Downloads' section)
It is nothing like what I have in the playcanvas editor or other webgl demos, so..
Thanks for the help.
