Screen Tear?

[3dfx]

For some reason I can see the outline of images in a lot of my games such as SOF 2 and NOLF 2 with my Parhelia. I know Matrox are aware of the NOLF 2 problem and it looks like FAA 16 is causing the problem. I was just wondering if anyone had a similiar problem? I'm using the 42 driver set any advice?
thx

Think it might have something to do with connecting via BNC?

It is an issue with FAA when fog is being used.
Tearing is something completely different, related to vsynch.

I couldn't keep FAA on in NOLF2. At 1024x768x32, with all options on, FAA would have been too much load for the later levels.

Ok cool is there any way of solving the problem in games like SOF 2 or are Matrox working on it for the next driver release?

[Kruzin]

If the game allows it, disable fog.
If not, disable FAA.

Turning off FAA 16 x fixed problem, do you think this problem will be fixed for next driver release? and has this been a problem since the original drivers?

No and yes

Do you think this problem will ever be fixed or is it inherently in the Hardware ?

I think I'm gonna
But I still luV!!! MA!!PARHELIA !!


P.S. Do you think it might have something to do with my BNC connectors? on monitor

no

That only pertains to when Vsync (Vblank) is disabled on the Gcard and the frame being outputted clashes with the Vsync (Vblank) setting of the monitor... ie especially when the Gcard's frame rate changes (dependent on the scene load).

For example: lets say Gcard is ~42fps and the monitor is set to say 85Hz you would see ~2x tears in the scene. If it neared less than that you would have an increase of screen tears proportional to the ratio between them..

Monitor refresh rate 85Hz

Gcard fps
= 42.5 = 2 tears in screen
= 28.33 = 3
= 21.25 = 4

etc etc etc

By updating to the 2kxp_102_02_003 drivers set from the 2kxp_102_00_042 I appeared to have fixed some of my probs, it is still there but less apparent. For me atleast it is almost gone in NOLF 2

I heard that if you get a bigger PSU it can help the banding in games

[Wombat]

Power supply issues were suspected at first, but it seems unlikely now. I for one, went from a 350W to a 450W unit (for other reasons), and the banding is still quite present.
