Red game 4:

[Apuly]

I see a total of 3 problems. 2 with your build, and 1 in your post.
The one in the post: greatgamer will always complain about (1,1) instead of (0,0).

The 2 with your actual build, 1 which apparently doesn't count.
1: The pistons in your screen cause lag. You could replace them with turned on redstone or something like that, enabling it to be a bit lass game crashy.

2: The build is hardly optimised for command block mechanics. For instance, you can make your comparator work with fancy command block mechanics. And I'm pretty sure that because of some of the properties of command blocks the GPU rendering could become quite a bit faster.

One side note, that has nothing to do with the build: I feel like this is the the bestest start for the command block CPU/GPU/whateverthefuck. If you would have taken it to the next level, with a triangle renderer for instance, you might be able to pull some people to the non-redstone side of redstone. The machine that you build here just doesn't do that.

Let's just stay unknown to each other.
