nVidia ForceWare 84.21 Drivers Released


Recommended Posts

You knew when installing X64 that it had crappy driver support. That is the only thing hold me back from using it.

Yeah I did. An for awhile there nvidia was updating their x64 drivers right along side the 32bit ones.... they've just been slacking lately.

:)

You have to install nVidia Pure Video (they have a 30 day trial of it on their site somewhere). Thanx, I will give em a try tomorrow.

The nVidia Purevideo program is the new name for the DVD player. It's an mpeg 2 decoder. On the site it says that, amongst others, WinDVD 7 supports H264 decoding on the 6600GT. It doesn't. I tried a .mov, it uses 100% cpu and plays really slowly. I tried a Nero one that nVidia has in their "showcase", WinDVD crashed.

This might sound really stupid, but I've tried clicking on the accept button to d/l the drivers, and nothing happens. I tried the primary site and all of the mirror sites and the button doesn't do anything! I clicked the cancel button, and it works fine.

Well when i play any movie file (including .avi's) with Media Player Classic my CPU usage sticks around %10.

its better to run driver cleaner in safe mode just to be sure u get rid of eveything

I have only done this once in the past 3 years, and I have not ever had any issues with just installing on top of older driver versions.

From my personal experience I really think the only time you need to run driver cleaner is when upgrading your card and more importantly when changing card vendors and/or makers. Also if you are troubleshooting some kind of system instability that you think may be driver related. Other than that, I just install on top of the older ones and never had any issues at all.

Also FYI for everyone else, they are not WHQL'd on my 6800 Ultra either.

By avis I assume you mean DivX or Xvid which are very easy to decode. H264 is very hardware intensive. The best software decoder at the moment is CoreAVC which can decode a 720p video with only 80% cpu used, but that's without decoding the soundtrack (AC3 passed through spdif). On the other hand, 720p Xvid uses about 40% cpu including the soundtrack.

I see what u mean now, just played the 1080p Silent Hill trailer (first H264 movie file ive watched) with MPC (using Quicktime Alt), I have these drivers installed and PureVideo, and my CPU was around %60 most of the time (sometimes went down to around %50 but never went above %80).

Unless u havent read, the 6600GT is now WHQL'd, they missed a file out of the original release of the drivers, they are now updated and have that file with them (check the filesize of the 84.21 file, if its 21MB then u have the old ones, the new ones are 20.9MB (new ones also have the light blue file icon)).

Not saying that getting the new release will fix ur prob with WinDVD, im just letting you know that PureVideo seems to be working for me with MPC and these drivers.

Thanks for the info (Y), now downloading the updated driver. 60% cpu on your CPU is decoding in software, there's no way it'd be that high if it was decoding it on the GPU. Note that I have a 2500+.

-- Nvidia says: * Before installing new drivers make sure you uninstall all NVIDIA display drivers from the Windows Control Panel. Browse to the Start Menu > Windows Control Panel > Add/Remove Programs and search for "NVIDIA Windows Display Drivers" or "NVIDIA Display Drivers" and select remove.

but to each his own. if something has been working for you, go with it.

Hey guys, im just wondering i have a x64 system, but am using 32bit windows xp pro... i also have a 7800 GT should i d/l these drivers or not?

Yep. (Y)

The only time you need to worry if the drivers are for 64 is if you are using the XP64 Operating System. The 64 bit drivers do not refer to your Processor, just your OS.

So until you update your OS to the 64 Bit Version, you are always fine with their normal drivers.

    • Forgive my ignorance, but the only difference I see here is that a USB-A is now a USB-C, so there are two of them. For the modern age (and I'd argue since 2020), most products would now come with USB-C as an option, if not the default. Display, charging, devices, etc on TWO connectors, sometimes all combined! So having 2 of those powerful ports is great for something this size! Meanwhile my Surface Pro (5) has a single USB-A port which I cannot even get display out to, instead relying on some Surface Connect dock which I don't have. That is a poor experience, not to mention expensive and not compatible with other devices. Thank God USB-C is mainstream!
    • wow. that color finally comes to Surface Pro. was always a little jelly when a friend had the sandstone Surface Laptop. I wonder how different this dune is from the sandstone. I'll be getting the dune version. always thought black and platinum were a little boring. I'll still have access to my blue Surface Pro 11 as it'll be a hand-me-down.
    • Looks a very subjective aren't they!? I like its simple design. I love the way Apple designs their products with function over form, minimalization, and simplicity over cluttered complex designs. Many, not all, of their products follow this trend, and the device becomes a tool rather than dominating the space. I do not however like their OS. I have never bought a Apple product, and while I'd consider the Neo for my wife, I am hoping there are better alternatives out there when her failing MacBook Pro 2017 finally stops. Fischer-Price is famously plastic, garish, and poorly made. Basically you're describing the Window Laptops the Neo competes against! This is how product design should be, and what Apple have often followed in recent years: https://tenprinciples.design/
    • Isn't that true for every codec? I remember having to buy a PCI MPEG-2 decoder card just so I could play DVDs on my computer back in the late 90s. AV1 support is still fairly new.
    • I'm no Apple fan, and have never bought an Apple product for myself. But I'd argue that where you think Apple is behind regarding an OLED display, that the vast majority of people out there wouldn't even know or care for an OLED. Apple have struck the balance well to create a price point that works, and I hope that PC manufactures, and Microsoft take notice. I'd argue that Asus will struggle to compete with the Neo BECAUSE they put in a more expensive OLED that many people won't actually notice with its deeper blacks. Most people wouldn't care either that their screen is stuck at 60Hz! When I bought a 4k monitor (future proof and for the space), my laptop could only push that out at 30Hz, and it worked fine for my needs for 1.5 years! Heck, the average human eye can't see more than 90Hz in many situations!! So while they are trying to differentiate themselves, and it may well gain them a few customers, for the most part, I think they're missing the point of what the Neo is for.
