Duplicated GPU Driver

[Joadix100]

Since i upgraded this machine to Vista (late 2020) i had one problem with the GPU, the drivers would install twice or duplicate at some point and cause problems, like the Internet Options menu not letting me use Hardware acceleration, only software, and the performance of videos not being great, i didnt expect too much from a 2008 low end laptop but as i saw more and more videos about vista and realizing that with my hardware y should have a better performance i started suspecting, in late 2021 i realized that the CPU had EM64T support, meaning it was a 64 bit CPU and not a 32bit as me and my mother (previous owner) thought, so i installed the 64 bit version of Vista and the problem disappeared (or i tought) because the Internet Options menu let me use Hardware acceleration, but after some time, it again swithched to software mode with no way to change it back, and here i am.

I have to say that the "Bus PCI, dispositivo 2 funcion 0" is the one you see when you enter device manager, and Bus PCI, dispositivo 2, funcion 1" only appears if you enable hidden devices.
This picture is from Aida64 (prooving that is not a device manager error)

Translation:
Dispositivo: Device
Funcion: Function
Adaptadores de pantalla: "Screen adapters" (GPU)
Graficos acelerados: Accelerated Graphics
Usar procesamiento por sofware en lugar de procesamiento por hardware: use software acceleration instead of hardware acceleration

Remove the drivers with this: https://www.google.com/url?sa=t&rct...ownload.html&usg=AOvVaw3-rWs3VvAYLRrGC9_Ttyl0

What do you mean Vista (2020)? It was released in 2007 and updates where discontinued in 2017.

I know, i meant that i installed Vista in late 2020, and reinstalled it more than once and the problem was always there, about DDU, it didnt work, when i install one driver the other one does it too.
i dont know if it is a bug with Vista or a hardware problem, maybe i have an AMD or Nvidia Laptop GPU but i dont know how to see if it does, in the manual it doesnt say it has one neither the web page.

The My Computers you list are for Win 10 so I can't tell what the system specs are for the computer you're using. What is the model number? If you have a discrete GPU, whether or not you can use hardware acceleration with it depends on the driver your using, since both AMD and NVIDIA discontinued the use of hardware acceleration support in "legacy" cards in their latest drivers starting about 6 or 7 years ago. For instance, I'm using a legacy NVIDIA card and have to use an older driver to get hardware acceleration for video transcoding and burning.

I updated my system specs so the Vista one is system one and the 10 one is system two so you dont have to check system two, i also have a link to the official webpage

Thanks for providing the specs. As you can see, you don't have a discrete graphics card. At the Acer link, it says you have a VGA driver. Per this paragraph 1.3.7 here-

https://www.intel.com/Assets/PDF/datasheet/313053.pdf

there's only the ability to attach an external Graphics Accelerator to the system. The ability to internally use graphics acceleration doesn't exist inherently.
Specifically, what graphics driver are you trying to install?

my problem is that i know what GPU my system has, but it is apearing twice in the device manager and maybe (it could be due to something else) causing the hadware acceleration to be disabled and locked

GPU usually refers to a graphics card that is installed. You don't have one. The graphics on the Intel chipset doesn't have hardware acceleration unless you attach a device to your system as stated in the link I provided. You only have VGA so the display isn't going to be great.

Have you tried deleting one of the devices and rebooting? You might want to set a system restore point before doing so.

i tried, but it just uninstalls both of them or reinstalls the missing one
i started to think that this is not a bug, its how its suposed to be, i checked my system two and the GPU driver is repeated twice
but that does not answer why i previously could enable hardware acceleration and now can´t do so.
now my main goal is to enable it again, so, any thougts?

I got looking around a bit on this and it may be that one device is the primary device (Device 1) and the other might be a device which can be switched to for graphics acceleration via software. On my HP with Win 7 Pro and Intel graphics, it only shows Device 2. However, someone said if you run Belarc, you may be able to see the other device but I didn't try it. Are the drivers for each device the same?

I would think that if the what I'm saying is correct, you would never see the usage of graphics acceleration since the switch is done automatically, similar to having both onboard graphics and a discrete graphics card.

the driver is the same, the only change is the Funcion from 0 to 1 and the memory reservations in the properties on device manager
now i am asuming that that is the way it should be, however i still want to enable hardware acceleration on the Internet Options menu, but is disabled and greyed out

What driver is shown for these devices?

As you can tell, I'm not an expert on this stuff. Where is the "Internet Options" to allow "hardware" acceleration. In my Internet Properties, Advanced, it has the option for Graphics Acceleration to use software rendering rather than GPU rendering.

yes, an in my Internet options the software rendering is turned on and locked

As was mentioned in section 1.3.7 of the link I provided earlier, one needs to connect an acceleration device to get hardware acceleration, if I'm reading it correctly. If so, maybe that's why you can't change it.

i could use hardware acceleration before whithout being conected to nothing, but at some point it just disabled itself and locked

Well, I can't tell you how many times people have said that they have a problem and are looking for a solution and the computer mysteriously fixes itself. Perhaps this is sort of the same thing in reverse.

You didn't say what the driver is for the devices.

 

[wither 3]

Not sure why you're not answering my question.

i just gave up

The actual installed driver should be listed. For instance, this is the latest driver I see for the chipset- 8.15.10.2697
