GeForce 6800 problems

[rbgrn]

I just bought a new eVGA GeForce 6800 the other day and am having 2 issues with it:

1) It inits into 3d mode just fine and is very fast and looks awesome, but if I try to change modes within a game, the game gets locked up at 60-99% CPU and I have to kill the process to quit it. The same thing happens when I try to exit a game... It hangs, but I can ctrl-alt-del and kill the process manually, returning windows back to the normal desktop state.

I mean, I _can_ keep running games that way, but I shouldn't have to. My old MSI GeForce 4 MX440 switched modes perfectly, so I don't understand what's wrong here. I installed the newest drivers from nvidia (61.77 or whatever they are.. new ones), installed DirectX 9.0c, checked my BIOS settings (all default + set to what eVGA recommends for normal / safe operation)

Any ideas there? My system never totally freezes; just the game/3d application can't exit back to 2d windows or switch 3d resolutions, and I can always pull up the process manager to kill the process.

My next problem:
2) I run a 1600x1200 normal desktop (standard 96dpi font) and have never had problems reading the text with my old card (MX440). Now the text is difficult to read with the 6800. Poor DAC? maybe. I'm not sure. I saw a few other people on some other forums were reporting similar problems with the eVGA card. It seriously looks like when you run an LCD at a non-native resolution and the pixels look inconsistent and chopped off, like some are thinner than others. It's really annoying.

Like I said, this also worked perfectly fine with my old video card, so I am at a loss for what could be wrong here. I'm running 75hz, auto-detect timing.. same as with my old card.

My system info:
Athlon XP 2600+ (333)
Epox 8KRA2I mb (via kt600 chipset) (latest firmware)
1 GB PC2700 DDR RAM
eVGA GeForce 6800 (128mb) (nVidia 61.77 driver)
M-Audio Delta44
Sony G400 19" CRT Monitor (analog non-dvi connection)
Windows XP SP1 w/all up to date patches
DirectX 9.0c
Nothing is overclocked, standard settings are used for everything.


Any help/info/advice is greatly appreciated!!!

Thanks everyone!

I have just bought the eVGA 6800 ULTRA from newegg
61.77 Driver
the only issue I have had is the card seems to lock up on Call of Duty online when things get heated with 5 minutes to go,on a 20 minute sestion.
Now my test rig only has 512mb of ram,so this afternoon I will do some more tests and see if 1GB of ram has any thing to do with it.
I will be switching over to an INTEL 3.2 Dell 400SC AGP 4X 1GB ram system from my test rig of AMD 64 3200+ 512MB K8V SE system
I am running Dual Dell 2001FP's 1600x1200

Why would you have 1GB in the intel but not in the A64?

Well, I found the solution to the lock-ups..

I installed the 65.56 drivers and all directx and opengl games work properly now. They're not official drivers, and I think they had to be modified to be english, but things are working well so far.. I'll report back if I have any new problems related to these beta drivers

NVIDIA doesn't distribute these drivers on their site, so you'll have to search around a little to find them. I got mine from http://download.guru3d.com/detonator/

You have to reinstall drivers after installing DX9.0c as well, that may have been your issue.

I did reinstal the drivers after directx and continued to have the issues. I'm very sure now that this is a simple driver bug related to my KT600 chipset and the 6800 GPU.

I'm having the same trouble, some games lock on video mode switch and esp. on exit. I'll check out those new drivers.

Specifically, i have a 2500 Barton on a KT400 chipset mobo.

Games, include
Medal of Honor Allied Assault and expansions
Homeworld2
Painkiller (i think)

Woot! 65.73 seems to have fixed the problem.
