Stutters flashing textures Continue after Fix# 3 - moan groan whine

[boleyd]

I thought I would capture some comments in the title.

Anyhow, installed #3 fix and I continue to see stuttering and flashing textures. Unfortunately, these are becoming signature items for Trainz. The stuttering is probably due to inadequate design of data acquisition from the disc. Flashing seems to come from windows and signs as the most noticeable items that are placed on a surface. I get over 60fps on the route that I use which is well populated with objects - grass trees and buildings. I have found no reasonable settings in Options to stop these issues. Video drivers one generation behind since latest had issues with video card resetting. Vsync or the trainzoptions limiter do not fix the issues. N3V seems to be able to deal with on-screen graphics and database issues ok. They also do well with assets. But when it comes to very technical and complex problems they, as the other train product's staff, fall short. They probably would like me to buy a faster computer and an SSD. Well that will not happen. Nor will there be any purchases of any DLC items. I really like trainz compared to the other Train program but no ability to fix issues that are universal and ancient is VERY frustrating. With each update you hope but ......

I am not seeking a fix (except from N3V). Rather just a rubber room to whine and moan.

Hi Dick,

Are the flashing objects flat objects on the ground surface? If this is the case then it's caused by objects being too close to each other. The technical term is co-planar faces or surfaces. It's actually a byproduct of your video cards inability to render both the foreground and background objects at the same time. To resolve this move the top object off the surface about .1m. This will let your video card render both objects without trying to put the images of both in the same memory space which causes the flashing.

If the problem occurs on buildings, this is also a similar issue, but it's a fault in the asset its self and needs to be resolved by the creator.

Sometimes there are video card settings that can help with this. Try some of the tri-linear buffer settings or some of the other settings in your NVidia Control Panel and what not. I say this because with my NVidia 680GTX, I don't have that issue and I may have played around with the settings.

My GTX 550 is ok with surface planes. It is the buildings signs and windows that are flickering. I often wondered if this was due to a lack of size of the values describing these elements on a vertical plane. Higher precision values might reduce this. Anyhow, thanks for the tip on the changes. Will give that a try now....

Maybe it's because these objects have textures that are uniform colors.
