Guide: Installing the 10.10a hotfix w/MLAA support on Radeon Mobility cards

Gentlemen, ladies, alien life forms, et al,

I wanted to put together a guide to install the Catalyst 10.10a hotfix drivers on Radeon Mobility cards on Windows 7 x64. After some system preparation, you should be able to get them running without having to hit F8 and disabling driver signing every time you reboot your machine. Standard disclaimer - Your mileage may vary in getting this to fully work on your machine. I am not responsible if something gets messed up on your machine.

NOTE THAT THIS GUIDE ONLY WORKS ON WINDOWS 7 PROFESSIONAL, ULTIMATE, AND ENTERPRISE. STARTER, BASIC, AND HOME PREMIUM USERS MUST USE DRIVER SIGNATURE ENFORCEMENT OVERRIDE, FOUND HERE

System Preparation - Disable Driver Signature Enforcement

Option 1

1a) Open a run dialog box (Win+R) and type gpedit.msc

1b) Expand "Administrative Templates" which is under User Configuration. Then go to System/Driver Installation

1c) Double click "Code signing for device drivers." Select Enabled from the top part and "Ignore" from the drop-down menu in the lower-left box

1d) Hit Apply, close down all the boxes, and reboot again

Option 2

2a) Open regedit and navigate to this key: HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows NT\Driver Signing

2b) Change the BehaviorOnFailedVerify key value to: “0″ (ignore, no quotes)

2c) Close regedit and reboot

Driver Installation

Now the fun part. We'll be doing the installation the old fashioned way, through Device Manager.

1) Install the standard Catalyst Mobility 10.10 drivers as normal if you've not done so already.

2) Download the "10.10a mobility try1.7z" file from here. The full suite of Radeon Mobility cards should be supported. (Credit to user asder00 from the Guru3D forums for creating the modified drivers)

3) Extract the downloaded file to a folder using 7-Zip. For the purpose of this guide, I extracted the files to C:\1010a hotfix\ DO NOT RUN THE INSTALLER FROM THE FOLDER WHERE YOU EXTRACTED THE 10.10a MODIFIED DRIVER

4) Go into Device Manager/Display Adapters, double click your video card (ATI Mobility Radeon HD 5800 Series in my case), and select the Driver tab

5) Click Update Driver, select "Browse my computer for driver software", select "Let me pick from a list of device drivers on my computer", click "Have Disk"

6) Click "Browse" then navigate to: C:\1010a hotfix\Packages\Drivers\Display\W76A_INF and select file C7106344.inf

7) Let the installer do its thing. It will probably complain that the driver file is not signed, install it anyway. Your screen might flash a couple times during installation.

8) When it's finished, reboot, and you're done.

Here's a screenshot of the working Catalyst Control Center:


And a shot of device manager showing the 10.10a drivers installed:


I've only tested Half-Life 2 to this point, but MLAA is indeed working. It reminds of NVIDIA's old Quincux AA. On-screen text is a bit blurry, but you don't notice it once you're in the game. It's definitely worth experimenting.

 

With this guide you would get the new drivers but not the CCC and other things I would think if you only update the display driver via the "have disk" method.

Also note that gpedit is only in the higher versions of windows. The VAST majority of us use home premium and that does not include gpedit.

 

This is why you install the standard 10.10 drivers first, which is step 1 of the driver installation part. The CCC that's included with those drivers works just fine after the hotfix is in place.

You should still be able to use the command prompt method of disabling the signature check.

 

the command prompt version is not permanent its required at every boot I think, but regardless if you want to make a guide you need to tell people how to do it and test it.

I made like 500 guides just trying to help

 

Nope, doesn't work, hasn't worked for a while either since W7 64 went official.

Have to disable driver enforcement at each boot pressing F8. Extremely annoying.

 

Will this work on the G73jh? Im already updated to 10.10. And how will the performance be? More frames per second? I play Tf2 and L4d2.

Sorry for the many questions amazing step by step guide.

 

As a G73 owner your one of the many that only have home premium unless you installed your own version of Win 7 Ultimate/Business so this guide wont work for now.

You can partially follow his guide and then supplement with the 10.9 drivers post we have in the G73 forums and get it working. You will have to use DriverReady or manually sign your drivers with this tool:

Driver Signature Enforcement Overrider 1.3b

Also note that when you enable "test mode" with that program its the same as the step 1b in this guide, it also gives a link to a 2nd program you can use inside this program to remove the "test mode" watermark on the desktop.

 

Not if you install the driver the way I listed above using the modified drivers linked to in the OP. I've rebooted at least 5 times before I put the guide together, and I've not had to press F8 once.

It should work on any Radeon Mobility card, even older models. The hotfix designed to enable Morphlogical filtering and surface format optimization, which can provide an image quality boost with less performance cost. Your mileage may vary. I think games look pretty good with it on, but the blurry text boxes are annoying. You'd have to experiment on a game-by-game basis.

 

You seem to keep forgetting majority of us do not have Windows 7 Ultimate. Your method does not work on Home Premium. As Vicious said for the rest of us we have to run it in test mode with Driver Overrider or use ReadDriverPlus.

I've had MLAA working since yesturday, so yes I KNOW also.

 

I dont like the MLAA anyways :/

Id share screenshots but fraps wont work since its a post processing effect.

If anybody finds a leaked mlaa.exe so that I can run the filter on some screen shots and do a comparison post please let me know.

I heard windows snip tool works, but not sure how/if that works in games.

 

My apologies. That is a royal pain. I tried a few different things on the second laptop in my sig, which has Home Premium but couldn't get it to work. I've updated the first post to signify that this is only for Pro and Ultimate users. Hopefully someone will find a way to work around this at some point down the road.

 

Already did its called driverreadyplus or sign your own driver files.

From the device manager you can see the files used by the drivers in which you need to sign.

 

Well i got the driver installed, but ccc still doesn't work sigh !

 

Yep I'm hoping TWL, TweakForce and rflair may come up with something, with some optimizations too! There mods for some reason don't need any workarounds, just install straight from CCC installer.

 

I have a Mobility 4650.

Is there any point to me installing this hotfix? Or does the hotfix only benefit the 5XXX series cards?

 

For the time being MLAA is meant to be run through Shader 5.0 which is DX11 only.

There are some who say they got it working on HD4xxx, but in game, it's all messed up, can't see anything. All glitched up, as said, you need shader 5.0.

Maybe many months from now they may backport to HD4xxx but with release of 2 generations of DX11, I wouldn't hold my breath, they may never do it.

 

Just a heads up, I think SC2 is one of the bigger games people are wanting MLAA for.

However there is an issue with textures vanishing, in particular the only one I have noticed but quite annoying is that the pylon power field is missing or only partially there.

So when trying to warp in units I am kind of guessing where I can do this. I found one other person so far to say he had the same problem and its only with the 10.10A drivers not the 10.10 WHQL.

Going to try a clean install with a different modified version of 10.10A and report back if its there still or not.

Yeah, just tried DNA drivers and the texture bug is still there if not worse.

I am just going to use 10.10 WHQL I do not see any advantage great enough to worry about 10.10a. You get a bit of AA but blur out many other things so you lose something to gain something and the net result is you gained nothing overall

I prefer sharp crisp graphics to blurry ones even if it has some jagged edges. Then again jaggies never really bothered me much in the first place on any modern game, it was only really bad in old games like in the HL2 era where a fence looked like it would cut you if you got too close. And games that old easily let you turn on real AA to fix the problem since they are not demanding.
