Why do I see no Windows 8 or 8.1 support? If I got an RTX card would I really have to re-install Windows to use it since I'm on 8.1?

I know 8 and 8.1 have less market share than 7 or 10, but it's still greater than Linux, Solaris or FreeBSD for desktops isn't it?

If you want to make use of the Ray Tracing features that the RTX cards support, you will need Win 10 1809.  So they answer is yes, you will need to upgrade.

Yep, another Windows 10 only feature!

Not only that but Microsoft Direct ML is coming Spring of 2019 and that will also be for Windows 10 and support inferencing into games and other applications.

Re: GeForce RTX 20 Series - Windows 8 and Windows 8.1 Support? 2018/10/07 16:44:16 (permalink)
Yeah, I know the raytracing feature only works on Windows 10 with the latest Direct X 12. I was wondering if the card works on Windows 8 and 8.1 at all since the driver list (as shown in the images) includes Windows 7, but not Windows 8 or Windows 8.1. Why list Windows 7 in the driver list, but not list Windows 8 or 8.1?
 
I've no interest in raytracing until more games utilize it. The performance of traditional "raster-based graphics" (I think that's what we're calling it now) is what I was more interested in since there is a colossal amount of PC games that are not using raytracing or even DX12 for that matter.
 
It will be nice to have such features in the future, but I'd rather not have to install Windows 10 immediately. Installing Windows and all my programs is one of my least favorite things to do. It is very tedious. Popping in a new video card and only having to install drivers for it is far less of a hassle than reinstalling absolutely everything. I will update to Windows 10 when I move to the Z390 platform since a Motherboard+CPU upgrade actually would require an OS update for things to function properly, but for a video card swap? I don't want to wipe the OS and reinstall everything for a video card swap.

That's so weird that it isn't officially supported on Windows 8 though since Windows 7 is supported. I kinda expected support for the older OS to be yanked first like with XP.

Userbase is nowhere near Windows 7 though. And I have to wonder: why are you on 8? I don't remember anything good about that OS.

I agree that 8.1 user-base is low, so it makes sense.

8.1 performs better than Windows 7; especially in regards to boot speed and SMT/hyperthreading performance. And doesn't have as many spying issues compared to Windows 10. For some people, it's the happy medium between the two, while the rest polarize to one extreme or another.

No, it doesn't make sense. I already addressed the low userbase argument in the first post because I knew that would come up. Offering RTX drivers for Linux, Solaris and freeBSD while dropping Windows 8/8.1 because "low userbase" is contradictory.
 
There was so much underhanded nonsense pressuring users to install Windows 10 that I can't help but suspect this is a continuation of it. Microsoft partially gave up on the Windows 7 holdouts for now stating they would support updates for Windows 7 up to January 14th 2020 then implement a monthly fee for continued support (essentially "upgrade or pay us to get security patches"), but presently the Windows 8 userbase is dwindling while mostly migrating to 7 or 10 thus 8 users are likely still a target of these tactics, tactics like withholding official driver support on popular new hardware for instance.

they probably withheld 8 support because although it has a usb3 driver built in, it won't be able to use the PPC driver, making the usb c's only use as a data port.

I hate most such limitation with software.
You can't look UHD BluRay on X299, we need Intel HD.
Imagine that, no RT on Windows 7. 
You need to remove old 1080p monitor from closet, to install Windows 10 1809, push 4K monitor on side and play 3-4 games with RT.

Without the latest Windows 10 Fall Update version you will be unable to take advantage of Ray Tracing such as that supported in Battlefield 5 if you have an RTX card. You will also not be able to take advantage of newer DirectX features from Microsoft.

raytracing is immature and windows 10 is a broken joke, these are entry level cards for the tech that will grow on future cards.
 
You also don't need dx12 for rtx, and you certainly won't need it for DXR once directvk advances.

I saw the strings in the INF too. But they should install on early builds of W10 and they didnt. (The driver installed without errors, but everything refused to run).

You SHOULD be able to install it as long as the correct NT version is in the inf. - Which it is.

I'll throw Windows 8.1 on a partition later and let everyone know. - I think NVIDIA is blocking them for no reason (it has nothing to do with Windows).

windows 10's a bit different. the driver code will actually refuse to run if a minimal wddm isn't met.

It would be great if you could find some time to test it on Windows 8.1.

I wrote to Nvidia support and they claim that installing Windows 7 driver in Windows 8.1 for RTX cards wouldn't work.
They do not recommend trying it, but that's kinda what you could expect tech support to tell you if they don't officially support that OS .

All hope in you Quad5Ny.
