[Q] Cyanogenmod Hardware Acceleration - G Tablet Q&A, Help & Troubleshooting

I have looked all over but can't seem to find a specific answer to this question. Does the latest build of CM have hardware acceleration? I know full hardware acceleration is not possible because Nvidia is withholding drivers from us. I have read that the CM team put together "partial hardware acceleration." What exactly does this mean? Thanks for the answers.

As far as I know, no. In fact, its one of the reasons I'm considering a throwback to Froyo, as it is the only place to find 100% acceleration.

is there a CM6 ROM with full acceleration or you mean stock tnt?

From what I gather, from reading other posts, the CM team was able to "accelerate the hardware" without "hardware acceleration" In other words, they were able to overclock to the point where the system would accelerate the video hardware. Think of it in terms of Windows, you can allocate more of the system memory to "push" certain aspects, be it video, cpu, etc. The problem with this is that to gain the "hardware acceleration" they needed to lose performance somewhere else.

He means any froyo rom. CM is a gingerbread based rom. Calkulin/Clemsyn, Brilliant Corners/Vegan 5.1.1, TNT Lite/Mountain Laurel, Gadam/Century eyes...take your pick, there are lots of Froyo roms out there. The Froyo roms are the only ones that will have 100% video hardware acceleration, because it is the only OS that NVidea provides drivers for.

i use beastly's rom, its non tnt, but is closest to stock that i have seen. not cm6.

CM just means Cyanogen Mod, CM6.x is Froyo, CM7.x is Gingerbread.
I was asking if there is a CM6.x ROM with working hw acceleration and basically asking if the limitation was the OS version, or the ROM, meaning you had to use a TnT variant which had built in drivers.
Since you list Vegan as one of the ones that has it (which is not TnT) then I have to assume a CM6.x ROM would also have working hw acceleration, is this correct?
edit: The reason I want CM so bad is because it is the only ROM where netflix works, so I could not only have hw acceleration but also netflix streaming in the same ROM.

Many people (myself included) have been complaining about this very problem for weeks (if not longer). Netflix only works 100% with CM7.03, so far. Which is Gingerbread. Hardware acceleration has only been fully enabled on Froyo roms.
You can get netflix "half working" with other roms using various patches, which basically will enable it to work, but there will be video artifact problems (big green line through video, colors shifted position ie. red and greens don't line up, etc). Vegan Rom Gingerbread edition can be hacked to work with it as well, however after you basically replace a bunch of libraries with the ones used on Cm7.03, which all just goes back to the following: Netflix really only works on CM7.03.
I'm currently using that rom exclusively because of netflix support, however the jittery performance I'm experiencing elsewhere (like, even opening the app drawer) is driving me crazy. I know the Tegra 2 shouldn't stutter like that.
Having real, bonafide Gingerbread on this device would be a g0dsend, as far as I'm concerned- not only would netflix, etc, work perfectly fine with full hardware acceleration, but also the new Skype video chat.

I've been having problems with netflix on CM7.1, can you point me to the exact ROM you're using?

---

actually, is there even a CM6.x ROM for the gTab? If not, why not?

On 7.1, I think you need to edit your build prop to make the app think you're an htc device or something.
On 7.0.3, it just worked out of the box.

apologies, I hadn't realized that there was a froyo version of CM...I've only ever known the GB one for the G-Tablet. I've never used it, however, because frankly (and my opinion is known on this) Netflix itself, is not worth having a specific rom, JUST to run it.
WHat REALLY needs to be done is people putting pressure on Netflix to develop a Froyo version of their app. When the app first came out, I read that they were simply testing the waters with the version(s) that were released, and that future development would be based on those reactions. Perhaps there is a way to contact NEtflix, explain your situation, and try to convince them to develop an app tat does work with the tegra 2 hardware and froyo OS.
Rather than modifying your firmware to work with the app, has anyone attempted to modify the app to work with the firmware? I know, personally, I've had problems running most popcap game releases. I'm not going to start messing with my firmware ot play Chuzzle, though...I'll just wait until Popcap releases versions/updates that work better. (oh, and ofr me, the entertainment value of Chuzzle and Netflix are basically the same, lol)

Thanks for the reply's. Now all we need is viewsonic to push nvidia to release the 2.3+drivers...
