[Flash and nvidia] Fulscreen very choppy

Hex editor? Isn't there something like a config file for flash?
What an idiocy!!!

Since the nvidia blobs don't use the SGI string it has no effect for those cards, but ya the the mere detection method use by adobe is retarded and speaks volumes about Adobe's coding competency.

This adobe blog is really the key:

The flash player does the unbelievably brain dead thing of checking the glxinfo vendor strings to make sure they do *not* contain the string "SGI". Flash hardware acceleration will only be enabled if the vendor strings do not contain the string "SGI". Incredible, huh? I guess this is the kind of idiocy we've got to contend with in closed-source binary blobs.

The advice given in one of the comments actually worked for me. Specifically, use a hex editor (such as 'ghex') to alter these two binaries:

/usr/lib/libGL.so.1.2
/usr/lib/xorg/modules/extensions/libglx.so

(or the actual binaries these files link to, if they are symbolc links. They were links on my system.)

They each contain one instance of "<null>SGI<null>" (plenty of the string "SGI" in other contexts, but ignore these). Change the single instance in each file to "<null>ATI<null>". Restart X, and you may just have hardware accellerated flash. It worked for me.

I tried this method on my Samsung NC10 (poor Intel graphics) and it did a magic, still thou i can say for sure, that Adobe flash plug-in for Firefox sucks, and if it is Firefox + *nix = sucks more. So blame Adobe, they think that everybody uses M$ IE.

OpenGL acceleration is also unchangeable disabled on 64-bit Linux systems. This really sucks, because I would like to be able to have tear-free YouTube videos.

I'm glad the old hex edit worked for somebody besides me!

I haven't had a chance to try the following solution, but from what I've read about the issue, my gut feeling is that this may well also work:

The solution below works with Nvidia 32 bit systems:

1. sudo mkdir /etc/adobe

2. sudo nano /etc/adobe/mms.cfg

3. Paste "OverrideGPUValidation=true" (without quotation marks)

4. Restart Firefox.

The above sadly does not work with the 64 bit Flash.

No, it should have been enabled for the latest alpha build of flash. However it's disabled if composite is detected.

Just checked the lastest 64bit alpha ... seems to still have no GL support.

32bit flash + nspluginwrapper + hex editor hack works fine here (with compiz running).

I was almost certain that I saw somewhere that the newest 64-bit alpha had enabled opengl acceleration.

I doubt that. It's not working for me, but more importantly it's not linked against libGL and the binary doesn't contain any strings indicating it loads libGL at runtime, either.

But is the 32-bit flash plugin? I believe that libflashplayer.so is using delayed loading of libraries.
