[Nexus 10 General] pushistiky:
For a few days i thought 100% yes - positive. Now im not so sure.

Screen was the main selling point for me. But now im disappointed.

After comparing with macbook retina screen (same image,on the same brightness) the difference is obvious: light bleed not only makes black glowing, but also makes colors much less saturated.

Both panels made by samsung, but they look completely different. PLS technology is supposed to be superrior than S-IPS, and it is, in retina display. But in nexus 10, it actually looks worse than S-IPS desktop monitor.

Nexus display still better than TFT.

DX11 class GPU ARM® Mali™-T604 GPU: APIs supported include OpenVG™ 1.1, OpenGL® ES 1.1, OpenGL ES 2.0, OpenGL ES 3.0*, DirectX® 11 and OpenCL™ 1.1.

GPU is great, but there could be a problem with tablet design. Playing modern games results in thermal Throttling in a few minutes.

I got to #2 in NFS: Most Wanted, but it was a torture, not fun. Usually, if you start with cold device, you can finish 2 races before slideshow starts.

You would not believe how bad it is.

Here is an example:

I slowed down and undervolted CPU to 600MHz/825mV to this test. Visually this reduced FPS (and supposedly GPU load) to about a half. But look at dmesg:

Game started at ~6162s, ~500sec later it started to throttle. Throttling, among other things, change memory speed and increases memory refresh rate 2x ( which slows down memory even further). Memory bandwidth is crucial to 3D graphics in 2560x1600.

This could be totally software issue, increasing temperature threshold, undervolt/underclock GPU and memory controller could solve the problem.

But if you want to enjoy this toy right now, you are out of luck.

P.S second issue seems to be solved, undervolting GPU -100mV and increasing throttling point to 85 C did the trick
