81.98 drivers just released.

Just testing these in X64.

Have been zooming and rotating my objects about like a madman in modeler. The objects have 3000 x 3000 image maps, and are reasonably dense. I'm not experiencing any lockups or frozen views, which I did with the other drivers. It also seems blazingly fast compared with the 77.77 drivers.

I'm still testing, and suggest you do so at your own risk, but so far I'm well pleased.

Just thought it worth a mention.

Just curious really, did any of you try the 82.12 drivers?

not me. I've read about problems with all of them until this one.

For me all the drivers have been fine, excluding the one cpu pegged at 100% issue that the 81.xx drivers seemed to have had. 82.12 has fixed that issue for me.

Strange...
I'm using the 81.67 Quadro certified drivers from nvidia and don't have this 100% issue you're saying. I have a quad 280 Opteron HP xw9300 on WinXP64. On the contrary, i'm very pleased with these drivers...

Tried 82.12 Lots. I think I might have actually posted here about them. Thought all was fine with them until I started experiencing the opengl views freezing up.

81.98 No joy for my setup

Lockups and frozen views contintinue for me so it is back to 77.77

Update.
I tried 82.12. LW freezes on model rotation. Back to 77.77

Just curious, are there anyone who is using dual core + nForce4 + GeForce 7800 + windows x64 AND the new 81.98 drivers and doesn't have ANY problems? Since I'm using 78.03 right now since those are the only one so far that haven't given me random lock ups or BSODs in full screen 3d-applications. Wouldn't want to try em out and find em do the same thing as the previous 8x.xx drivers...

Niklas,

I didn't have my spec up before (see below) , but I'm in XP64, and so far haven't experienced lock ups or frozen views. I am still testing though, so we'll see.

Sorry about that 1/100. Sounds a bit ominous. Will see how mine goes. I'm guessing you've already tried all the hotfixes and patches, mentioned over the last few months? I have and maybe that's needed as well.

I see on the Gurur3d forum, that some poeple are able to work in corel paint shop pro and some aren't with similar specmachines.

A bit tiresome I know.

i disabled multithreading for ogl-apps in the registry, now everything's fine, i can work with lw and play some new games. this is how i did it:

1. Go into Regedit and determine the current primary display card by looking in HKey_Local_Machine\Hardware/DeviceMap\Video and note the GUID (global unique indentifier assigned by Windows) for the entry "\device\video0" which is the long string at the end of the entry in brackets { }.

2. Edit HKey_Local_Machine\SYSTEM\CurrentControlSet\Control\Video\{guid}\0000, where {guid} is the number derived from the above step.

3. Open the "0000" directory and enter a new key called OGL_ThreadControl and give it a value of 2. This will disable multithreading in the driver for all OGL apps.

Then again I've never experienced that stuttering effect that everyone else seems to have :) Perhaps it has something to do with my dual single cores as opposed to dual core..

Nvidia has a strange way of labling drivers. Every now and then I've noticed that lower numbered drivers (that are officially available) are actually newer builds than the higher numbered beta drivers. So perhaps some advances made in 82.12 were taken and put into 81.98 along with fixes that helped improve OpenGL stability.

RPG, you did post about them (82.12), but they worked fine for me and fixed that CPU thing..

Anyway, ever since Nvidia got the bright idea of using multithreaded drivers (which I hear is pretty impractical, though I dont know the whole picture) The drivers have been fairly messed up. Hopefully Nvidia will get the hang of coding for multiple threads (on this level) soon...

Interesting useful info guys Thanx!
Any of you AMD Dual core user also using MotionBuilder? Any issues with slow repsonse versus Intel?

We had issues here at work with motion builder and dual-core AMDs. We had to install the new AMD CPU driver and it fixed it for us.

Well finally took some time to try the "new" drivers...

Unfortunatly my system still hangs when running LW/Modeler (8.5) and trying to run a WMV or DiVX file :banghead:

I am not sure where the fault lies, only seems to happen with LW in the background, but I do suspect it is related to the new series of drivers... As an added issue I cannot try older drivers since they will not properly function with my 2nd HDTV monitor :banghead:

Bah things worked fine when I still had an old Amiga RGB monitor as 2nd monitor... old tech rules! :cool:

These "new" 81.98 drivers do fix some other minor glitches I had with the previous ones (which the 82 betas also had)...

Speaking of the 82.12 Beta drivers, they ran fine here, no issues other than the ones I mentioned above, no stuttering either...

All in all I can't really say I see tremenduous "speed" differences over some prior drivers (70 series) and these on my dual xeon HT system...
Perhaps right now it is more limited to (opengl/directx) gaming situations atm than OpenGL software...

Bring on the new touted mpeg-4 accelleration tho! I could use that! :)

Suddenly realised I had an update for my freezing issues ...

Running the new 83.62 quadro drivers now (slightly modded the installer to work for non-quadro cards), and gone is the nasty freeze problem...

All runs very smoothly now, no problems, did not even go noticeably backward in FPS/benchmark tests, although I never do thorough runs, don't care that much for those kinds of results...

Now there is a slight issue with the new 83 drivers though, they redid the video-accelleration in a way that now the 2nd monitor will no longer get full screen video first off, its back to dragging a screen :(

But alas thats not Lightwave related, on that front all things are (back to) a smooth ride!

Yep, I'll second or third that.
The Forceware 83.62 is the first driver to work for me since 77.77.

No more freezing. It is a joy

Posted above. Went back to Modeler. Screen Frozen. Back to 77.77 for me.
Sorry for raising hopes!
