HD 3000 - apparent hang in main graphics engine

[StudioK]

I don't think the freezing is unique to Hackintosh. Apple hardware is afffected, too. I have the same symptoms running LION on my iMac. And I'm not alone.

Here's a thread I follow on the Apple Support Community forums (100+ pages now):

F**K THIS S**T

Bought a SAPPHIRE RADEON HD6670 for 90$

Shoved it up the PCIeX 16X

Booted up using GraphicsEnabler=no

FTW

To be honest, in one week I never saw any glitche. Only some freezing, about 1 time a day (working 16 in 24h) and it allways happen when I am using google chrome.

Do you think a hd6870 will solve the freeze problem?

hello,

i'm having this issue on a notebook. this issue rather seems to occur far less on 10.7.1, but it still does blow up the whole graphics engine from time to time.

have there been any new developments?

/edit

seek and you shall find.

so this particular patching suggested by revogirl is a huge improvement, though still not lag and artifact-free, it's still way better. i patched it down to 256 mb on 10.7.3. mission control is unusable and the menubar (just the icons on the right) triggers the hang.

i used to have a laptop with discrete graphics and never saw the hang. then i got a lenovo 420 with i5 +HD3000 only (company provided) and it hangs all the time (lion 10.7.3 or 10.7.4) ... so much so that is it unbearable (un-usable) when using the LCD screen.

the only way i can use the laptop is:
1) use external monitor (without extended/mirrored screen on LCD = shut lid)
or
2) remove AppleIntelHD3000Graphics.kext (and use the non-accelerated) and use standard/default graphics.

this mode works for office work and browsing - some video apps wont work. But atleast I can use LCD without any buffer hangs.

searched high/low for a fix/resolution. did all kinds SNBGraphics kext patching to no avail. ... i rarely get any glitches - but the freezing is/was a killer. got believe it is an accelerator driver issue.

may have to ditch the company box and get a new box with discrete card. Not sure if HD4000 will work any better ... waiting to see how Ivy bridge (with hd4000) pans out for folks.
