We can force the Nexus 7 to use its GPU to render 2d graphics. Nasa Developer Options-->Force GPU Render. Improves 2d scores by more than 400% (from 233 to 1000).
Then I decided to run quadrant for S and G's.
I wasn't expecting higher bench scores with the fix so I did the benching last. I tried that mod for a faster response from the UI. I also don't have any games currently running.
If I'd run games, I think stock can run anything that a modded Nexus could if only with a small difference in frames per second. The kernel modifications affect the CPU and I/O areas more than graphics. 2D graphics can be boosted by just enabling the [force 2D rendering to theGPU] option. I just like my devices performing more than what was paid for with a little tinkering. Because it's already there, it's up to us to make it work. Thank Google for being run by geeks first and businessmen second.
