Strange textures in parts of Rez #324

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?

1st instance

1: Play through Rez to Area 2, and fight the boss.
2: Get to the point in the boss fight where it surrounds you and sends the 
barriers at you.
3: Observe background texture flickering and flipping between colors. Also 
observe your character coming in and out of view in time with the texture.

2nd instance

1: Play through Rez until you come across a network opening.
2: Move the camera around and observe as the network opening and the lens flare 
that the network opening creates makes a big square boarder around them.

The expected output is this: http://www.youtube.com/watch?v=yqj0LETcFgI
This is Rez run on a real Dreamcast (or PS2, I can't tell, but it doesn't 
matter, it's the normal behavior). Skip to :40 and compare to the attached 
pictures.

What version of the product are you using? What build? What plugins?

I use version: 1.0.4 r86

My system specifications are as follows:

Operating System: XP SP 3
CPU: Pentium D 820 (2.8GHz)
Video Card: Nvidia 8500GT (overclocked: 630MHz core, 1260 shader, 375 memory)
Sound Card: SB Audigy 4 (non-pro)
Memory: 2GB DDR2

Please provide any additional information below:

Please note, the colors are different than normal. This is because I was 
running Direct Assault with the Ambient color scheme turned on at the time, and 
is not a malfunction.

To more specifically describe the problem for those who have played Rez, when 
you are fighting Mars and it closes around you for the first time and shoots 
the lock barrier things at you, the inside of it is normally white (like in the 
video). When it does this a second time and shows itself, and then makes webs 
to shoot the pellets at you, the inside is a kind of shifting dark blue color. 
In play in the first part, the texture flips back and forth between the white 
background and the dark blue background, which is not supposed to happen.

In the second instance, it's usually not noticeable if you are in a layer that 
has a lot of nothing it it (because the lens flare's background is the same as 
the whole layer's background), but if the lens flare goes over something 
brightly colored, it's definitely visible (see photo).

I don't think they're related, but what do I know?

Changing settings (disabling dynarec, fiddling with PowerVR D3D HAL, etc) 
doesn't have an effect.

This seems like something that would occur in more games than Rez, so it would 
be appreciated if this was investigated.

Keep on being awesome, nullDC guys!
