 Hello,

Im having trouble with WWT. When i run the program, the telescope images display then disapear very shortly after. The only way i can view them momentarily is by zooming in and then out  which repeats the same flicker/missing images.

 My rigg is as follows:

Antec Truepower 1000W Quattro

Asus Maximus Extreme (X38 chipset)

Q9950 @ stock ( 2.83 Ghz)

Sapphire 4870X2 @ stock

OCZ 4 GB DDR3 running in Dual channle configuration @ stock (533Mhz)

 Windows XP Pro 64bit SP2 /w updates

.net2.0 sp1 installed

Latest DX9c

Catalyst 8.9 Drivers 

WWT 2.1.8.1

 No other programs running in the backround.

 

This never happend on my Laptop which uses a low grade integrated GMA950 video adaptor so perhaps that is my fix.. but id much rather use my gaming computer.

I had been waiting for ATi to release their new drivers (8.9), and so i was excited to see if they had fixed this problem, but it seems they did not.

I even submitted the problem to the catalyst feed back program while i was using 8.8.

 
I really would love to use my main PC for WWT.. is there any info regarding a fix, or an acknowledged bug for wwt flickering with ati products?

 

Thanks.

 

Unfortunately WWT is not supported on Windows 2003. Please see this post: WorldWide Telescope minimum system requirements

i remember i read that xp 64bit is based on windows 2003 server so could that be why its not working for me?

 

 Ummm anybody out there?

Hi Crusid,

 

This sounds like a video card issue. What is the model of your ATI video card?

 

Thanks,

 Hey Chuck,

 

I was thinking that must have something to do with it.

My Ati card is a HD 4870X2 which has two 4870 GPUs on one video card using Crossfire.

Its fairly new - was released on aug 12 of this year.

 

 

installed the new ati 8.10 whql drivers and it’s the same problem - also tried 8.11 RC1 Beta drivers with no difference

 Just Tried to install the oct 29 08 update for WWT - Same problem - Star Images Flicker then disapear, Planets do not seem to flicker.

ATI HD 4870X2 2GB DDR5 (uses Crossfire on one video card)

Ati Catalyst Driver 8.10 Whql

XP64 SP2 

.net 3 with sp1 update.

 Updated WWT yesterday to the latest version. the same problems are there. images flicker then disapear.

Im using the latest ati drivers 8.12 whql ( awaiting 9.1)

 I have come to the conclusion that the reason it is happening is because im using windows xp 64 bit.

The reason i say this is because i have talked to an ati catalyst beta tester who has a 4870x2 like me, and his WWT is aparently working fine under vista.

 

so basicly WWT does NOT support windows XP 64bit.

 

If anyone can prove me wrong go for it.. id love to hear if some1 else has wwt working on windows 64bit.. if it does work for them in xp64 then that means it is a specific ati driver xp64 problem.. but if they cant..

 then the WWT developers should either state that xp64 bit wont work with wwt, or look into the problem and try to fix it!!!

 

thanks.
