I had the stock ROM with some the mods such as rooted and install unknown apps. I was happy with it but once I tried cm10.1 yellow kernel or the cm10.2 with the archdroid optimizations, I will never go back. I would recommend cm10.2 with the archdroid optimizations unless over clocking is important to you. If OC is important check out the yellow kernel ROM.

I used to use Boat, too, but now I use Javelin. I recommend you check it out. Also make sure you run trim after you get everything installed and set up; it could make a difference.

I think on the HD+ there's something wrong with the video driver. Because I agree as well that with CM11 (any version M or nightly) the OS seems more responsive but video transitions and anything involving the screen updates is a dog. Try playing games like PvZ or some others with specific types of video needs and it's just a wreck. I made a video to highlight my Nook HD+ vs Kindle Fire (first generation slow as dirt) with the KF boot screen making the HD+ cry. You can see when I page back left after paging right the HD+ stutters trying to load the mostly empty page too.

Nook HD+ has a 1920x1280 LCD. That's a lot of pixels to render and it is a bit too much for the TI OMAP 4470 to bear it seems. Most high performance computers don't even render that many pixels.

The Kindle Fire HD 8.9" uses the same CPU/GPU and it doesn't have issues doing the same tasks. As the OP stated too the stock rom handles the load better too. I really believe we have a driver or memory management issue.

Could be. Jon Lee of the Yellow Kernel thread has done some changes to the PowerVR and Vivante GPU drivers but it hasn't really changed much as far as I can tell.

He also suggested using the "Force GPU rendering" setting in developer options but that has some caveats. It forces apps that aren't configured to use GPU rendering to do so, but forcing things doesn't always work out as you'd like. Some apps use the GPU(s) already.

We have smart people working on the kernels here and if whatever causes the graphics lag was obvious/addressable it would probably be gone. I am positive that resolution is part of the problem. I've used lower end OMAP4 devices like Nook Tablet with 1024x600 and they were much smoother.

Games aren't a really good way of deciding what's happening.

They can have different quality settings that there's generally no menu for, so its automatic picking for quality. Historically at least, Real Racing 3 would pick it wrongly and thus the game would have bad framerate on the nook hd+ needing use of a 3rd party app to force the game to lower graphics quality.

I typically agree with this statement but if you view the video I posted in my other thread about this topic it's clearly apparent that an old as dirt, 1 GHz, 512mb, very first generation Android tablet running the exact same OS release smacked the crap out of the HD+. The Nook HD+ as is, is an embarrassing device running the non-default OS. The point of this is to ensure someone is aware of this and to see if anything can be done about it.

I haven't tried an emmc install of cm, only dual boot Jelly Bean and KitKat sd cards. But they break some of my regularly used apps, hence no emmc install.

But what I haave found is replacing the stock launcher with Holo launcher really speeds up stock. And Swapps task switcher lets you access recent apps. I'm not sure how it compares to an internal install of cm though, but I'm happy enough with performance.
