Flickering effect on some objects in OR

[plethaus21]

One problem I've not been able to get rid of with any combination of settings in OR is a flickering or "strobing" effect on some objects, such as these grass objects in SLI's Seligman routes:



To describe in more detail, it looks like the texture is being lightened and darkened between every frame, almost like the 50hz "hum" from fluorescent lights. Note that I'm not referring to the "sparkling" effect that can be cured with aggressive SSAA. This is something else.

Some other objects will do it at random too, like certain buildings, fences, trees, etc and it seems to come and go at random.

Noticed this with all OR builds I've tried from 1.0 onwards.

It could be one or more things that cause the issue. First is the object's mip bias, which may be set too high (-3 or -2, instead of the recommended -1 or 0), and the another is how MSTS and ORTS draws objects containing alpha with basic transparency - everything with hard edges tend to flicker or be jagged. The latter, however, can be overcome by adjusting your video card settings, such as to force a higher AA and AF. This will smooth things out considerably, but at a cost to performance (experimentation is the key).

On the Options ==>Video try unchecking Model Instancing and see if there is a difference. If it does now you have to make the choice, performance or flickering as Instancing reduces the video load. Your mileage may vary.
This 'flickering' effect has been discussed a while back at the Elvas Tower Open Rails forum.
Looks like your diesel's smoke needs tweaking too.

Running my DB-Tracks version of the Seligman-2 on my WIN-7 Pro, i5, GTX 560Ti computer shows little flickering of its grass in ORTS and none in MSTSBin.
