QT 7.6 DEFINITE MOUSE LAG FIX for ALL 8800 GT/GTS 512 & 8600-8500-9800 series

[spanakorizo]

i see there is a conversation about flashing the card (8800GT)

is it safe cause i play often games in windows so i need to know before take the risk

a long time i have strange lag with osx that appear after heavy use of GFX apps (final cut,motion,after effects etc)

so i blv that responsible for this is my 8800GT and im ready to flash

when the OSX boots is super fast,no lag,windows minimize full frame rate, i see no drop

 

i found that thread in another forum (bios link is inside, check it plz or suggest other)

http://forums.hexus.net/apple-mac/133400-m...-flash-mod.html

 

but before i proceed need to listen other stories and maybe a fast guide

 

also checked my BIOS with nvflash and i get this error:

ERROR: PCI BIOS not present

 

card is not oc'd ,twintech 8800GT 512mb

 

windows main os will be XP 32bit

leopard is 10.5.5

this has been asked and answered many times... read through the beginning of this post.

[luxus]

perhaps i am a little bit slow...

does it works on a 8800 gts 320mb?

and where i get the bios?

 

sry i am tired... perhaps i better should come back when i am not so sleepy

[cyclonefr]

no it doesn't work on 320MB (G80 is different)...

 

But GTS 320MB isn't affected by the problem as far as I know.

[spanakorizo]

ok im ready to flash but please check my original 8800GT rom file size (extracted with nibitor)

is it ok to proceed?

i say this cause the mac rom is like double size

 

AND AT LAST:

after flashing what will happen when i'll boot into XP?

"found new hardware" etc, or everything the same way was before flashing?

 

please advice

 

EDIT: i did everything with the freedos cd and at nvflash --check i see that i have:1024Kx1S , so is is ok to proceed:

1 farther question:

2D.rom with NiBiTor says "unknown rom etc"

but 2D3D.rom look good and recognized like the old one

 

should i flash with the 2D3D.rom?

3D.ROM from the first page should be the same size like yours.

 

XP will redetect your graphics card (vendor ID changed) at first reboot. Downgrading the firmware will also disable HDCP via DVI support in Windows XP/Vista.

Is there away i can use my hacked itunes binary with quicktime 7.6?

i just finished burning the freedos boot CD , and i am ready to reboot/flash

BUT with 2D3D.rom inside (cause it looked better on nibitor!)

advive please asap if it will be a failure for both pc/mac so i don't proceed

 

what do u mean HDCP will be disable?

my tft 19'' monitor is connected through DVI port, will this stop work?

what am i gonna lose ? ( do i need it only for Blu-Ray etc?)

 

EDIT: flashing with 2D3D.rom everything ok

removed the key from boot.plist , but osx will boot only in safe mode

reflashed back to my original.rom

 

i'm gonna try again

CAN I USE THIS ROM? :

http://www.neowin.net/forum/lofiversion/in...hp/t639884.html

[spanakorizo]

so

after flashing with 3 different bios, no luck (2D3D.rom 3D.rom mp8800gt.rom)

osx boots but with no qe/ci and nvidia card 32mb

nvflash looked like it was flashing correctly, and everytime after --check ,the new bios was in

i dunno why

 

ofcourse i removed any nvinjekt and 8800GT key from apple.boot.plist

 

iDeneb distro (10.5.4to 5.5) won't even boot, i managed to boot with a boot132 installation i have for testing

so this would be closest to the "real" thing (updated to 10.5.6 without remove/edit anything) but still no luck

 

any thoughts?

buy a Mac...LOL

 

Well at least try the disable kext as described above, or a different video card

[cyclonefr]

@spanakorizo : you still need INJECTION.

 

For your information, PC use BIOS, not EFI, therefore the EFI rom isn't loaded/used at all on a PC and we still need injection.

 

So no matter which rom you would try, you'd still need injection on a PC (but obviously not if you put the card on a mac pro.

[lensboard]

ofcourse i removed any nvinjekt and 8800GT key from apple.boot.plist

 

Missed this, you still need the inject

[adamsweeting]

I just need a clarification of the above !

 

Since I have a dual boot (vista) can I modify/flash my nVidia 8800 512k GT Over Clocked using Nibitor or do I still need a bootable iso?

 

If so what's the procedure using Vista/Nibitor?

 

Thanks!

NiBitor is just the BIOS editor... to do the flash you need to boot into DOS. NVflash is a DOS program!

Thanks for the info...much appreciate it!

[spanakorizo]

so i must not remove the efi key at apple.boot.plist?

and how am i supposed to understand the "difference"?

only typically?

 

anyway, i add the key again/flash again, and i'm gonna test a lot

 

is it ok if i use just efi key and not nvinject kexts?

 

EDIT: flashed again with 2D3D.rom and now i post from leopard

after effects running,motion,flash CS4,a lot of apps, minimize windows etc i see no problem

i'll keep it up for long time and i post my experience

 

as i said, my problem was that after heavy use (gfx apps), osx become laggy

i hope this helps things out

[thepiecesfit]

8800gt here boot 132 method, tried the disabler and erasing AppleUpstreamUserClient.kext . I believe it is the display driver some how not perfectly working with 10.5.6, since i get lagginess when turning on my TV connected to DVI 2 (sometimes) . The mouse still jitters for me despite the Definite fixes.

 

No mas for me . Still looking for a fix

[spanakorizo]

back to windows

after messing for 1 hour with heavy use of videos, gfx applications the lag return

it's like when it starts u can fix it only with reboot (or log off/log in)

 

description of the lag:

slightest but u can sense it when it comes

specially when minimize windows or use spaces, dashboard

like osx drops frames and no fullframerate is used

when it boots is super fast (if it was laggy from the 1st boot i would accept it)

 

i will make a video with osx how fast it is when it boots and the lag after

[spanakorizo]

NewJ_Project_1.mov

beggining is when osx boot and u can see how fast it is (sorry for bad quality)

after 25'' i captured small video with lag

windows minimize drops frames and in order to feel good again it needs reboot or logoff

 

EDIT: after flashing again with the mp8800gt.rom and full testing on 10.5.6 boot132 partition i see no lag

i had open like 20 apps together (photoshop,illustrator,after effects,motion,final cut,poser,soundbooth,soundtrack pro,quicktime,itunes,dreamweaver,iphoto,iweb,idvd,imovie .. .. ) and there was no problem

this test installation is in a very old 80GB ide disk

osx now feels stable like hell!

carbon copy and i'll move it to the raptor

[thepiecesfit]

So the only solution is the update the eprom on the card? Does it still work in windows ?

[spanakorizo]

for the 8800GT i would say yes

i reflashed before just for checking back to the original bios

and i had the lag, even with the disabler.kext (dunno why)

then reflashed back to the mac rom and lag is gone

[ksong]

hi cyclonefr

i try mod my bios ,but failed ,can u help me ?

You guys should just use the provided disabler.kext. No reason to flash your cards now.

 

Thanks !!!!! alot!

 

But i don't get it 100% (though i thought that my hours of research at least provide full "how to install a kext" knowledge:)

 

Problem is: I installed it with kexthelper. Rebooted with -f flag. System Profiler now shows Disabler.kext loaded under Extensions-Tab, but there are still AppleIntelCPUPowerManagement and AppleUpstreamUserClient in the list....

 

I had a CPUPowermanagentDisabler.kext (not sure about the exact name) too, but i read elsewhere you have to delete it, after installing Disabler.kext - deleted, again repaired permissions, booted with -f .

 

Still those not wanted kexts show up in SystemProfiler.

 

This drives me CRAZY.

 

PS: I THINK (can't fully remember) it used to work, but i reinstalled Combo 10.5.6 + all other updates that came after the 10.5.6 release with Pacifist using "update" yesterday. (still trying to fix that "Screenflow won't launch + no crashlog issue). Now my above described method of installing the Disabler.kext which blocks those 2 kexts doesn't work (cause i assume they are loaded since showing up in SystemProfiler / Extensions)

[iamhappy]

No clue what i did in the meanwhile

 

AppleUpstreamUserClient.kext is gone under System Profiler/Extensions BUT

 

AppleIntelCPUPowerManagement.kext is still in the list....

[Nemskiller007]

Sorry but i have MAC OS Retail Leopard X.5.6 and i don't have AppleUpstreamUserClient.kext, i can't find it !!!

But i have lags with Itunes and Quicktime....

I have a Geforce 9800 GTX+ what i have to do so ?

[secros]

Same technique, fixed.

 

thanks!

 

another successful flash here....

now updated to quicktime 7.6 and system runs without mouse lag

 

my card is Foxconn 8800GT 512MB

 

how to-

 

1. Use HP USB DOS Disk to boot

2. "NVFLASH --check" to check if rom size fits

3. "NVFLASH --save old.bin" to save original rom.

4. "NVFLASH -4 -5 -6 MP8800GT.rom" to flash

 

there seem no any noticeable difference from original bios(from boot to leopard, I didn't try windows yet)
