64 bit - why dedicated GPU?

Post by Paradise » 2017-08-07, 11:07

Since over the years i switched from Waterfox to Cyberfox and now Pale Moon i wonder about:
These downloads are native 64-bit versions of the browser, designed for 64-bit versions of Windows on modern hardware with dedicated GPUs.
If you are running on embedded graphics or a lower-end laptop, you may want to grab the 32-bit version instead.
None of the other 64 bit browsers where talking about dedicated GPU vs integrated GPU.

64-bit video drivers on low-end/mobile hardware or integrated GPUs often leave much to be desired. Pale Moon x64 is designed to run best with a dedicated GPU (not a dual-GPU setup either). It's a strong recommendation to prevent headaches down the road.

So i guess most people then use the 32 bit build.

To bad because the reason switching to Waterfox a couple of years ago was to have a 64 bit browser.
Even with a dGPU it does not make sense to disable the iGPU in the bios.

Also today normally the 64bit video codecs are a bit faster, less demanding.

It's up to you. this is a strong recommendation. If you insist you can use the 64-bit version on an iGP hybrid system, but the x64 Intel drivers are notoriously bad dealing with dedicated GPU drawing surfaces composited into a desktop. So if you run into trouble on that kind of system, don't be shocked.

There's nothing wrong with the 64-bit browser, and there's nothing wrong with using it on a normal desktop setup either. In addition, there's nothing wrong with the 32-bit version either and it will do just fine for every normal usage scenario of the browser.

Sorry if I don't understand really what you mean by this sentence (I'm German).

I know people are using iGPU and dGPU together on HTPCs and video work to spread the workload. They use Intel Quick Sync for one thing and CUDA for something else at the same time.

How would that work exactly?

If i remember right for example you can use Quick Sync to stream and Nvidia NVENC for recording at the same time.
Or editing software can use one for the preview and the other for encoding.

There was a program at the time when the Intel iGPUs game out where you could set what program should use which graphics card.

Interesting, what are the issues (performances, hangs, glitches, tearing…)?

Is there some way to determine if the computer is affected by such driver issues?

Anything from drawing glitches to BSODs.
