It really came out quite well...performance was also good
There were some issues though->
1) Don't know why there is some artifacts on the right half side of the image as you can see.
2) Also this is a modified hello shader example So you can see the blurred fps counter on top left. It was processed as well .So how would I Exclude it from the post processing . Else it would consume the GUI too.
Unfortunately I was not able to access my account
So I had to create a new one . I forgot my password and when I used forgot password option , then while renewing the password , it gave me "Invalid activation Code " Error.
