Your computer is having issues with shadow mapping.

 

[WiNdE]

Not that I condone conversions, but has anyone had a try to get the whole TDU island, or parts of it, from TDU into Racer

Some really nice areas on there!

I really like the run across the desert part to the west, and it rises up into some small mountains and has a switchback section and so on, then comes back down the other side and onto the flats again.

OH GOD YES!

I have this too, i dont know why it's happening, the shadows more than about 50m ale flashing... :/

OH GOD YES!

thx god and mr. dave

Just about everyone has that flashing shadows problem, looks like a Racer bug for Ruud to work on!

 

[Raphael Buthmann]

it's shadow frameskip and it's configurable at racer.ini Set it to 0 and don't flash any more, but performance issues can appear.

Or it might just be geometry/shader issues on the track.

I'm having some really nice results with CSM on tracks that are really solidly built... I do still get flashing, but it's nowhere near as bad as in that video above.

Hmmmmmm... clearly some optimisations to come from Ruud over the coming months, but I think that we also have to make sure our tracks are up to scratch too
It's an effect that relies on good authoring of the content that uses it... unfortunate in some ways as some content just isn't designed with shadow casting in mind, yet when it is done, stuff looks really wonderful!

I can't find where to find "shadow frameskip" in the racer.ini file, I need directions, please!
I adjusted the min/max values of "Throttler detail limits" in Racer.ini and the shadows all disappeared, I don't know why!

[Mr Whippy]

I wonder if the split jump is simply flickery due to the calculation being different every other time it calculates, or if in some cases/tracks it is simply doing the split, rendering it for that frame, then leaving it blank until the next calculation? Ie, it's not sustaining the last calculated info for 10-20 frames?!

It might just be a bug if so...? Hmmmmm

 

[Raphael Buthmann]

when I played the shadow map with splits in a sampler, with 2048 resolution,9 splits,nothing was flashing,200 fps and high quality. I don't know why on racer it's ~45 fps and all things flash "/

 

[Mr Whippy]

Did you configure new splits, or just change the number to 9 from 3?

 

[Raphael Buthmann]

I was on other software. A sample,was not cascade shadows I think,was the normal one. I think it's better than cascade,or cascade can be a second option.

 

[Stereo]

Can't tell what causes the flicker, it happened for me once on Carlswood but the next time I started Racer it didn't. I was editing the car shaders but not the track ones.

The cameras are completely dysfunctional in replay mode with 0.8.10, track cameras do not follow the car and I edited a lot of bits out of this video where it was just staring at a single tree for a while.

New video card means the new graphics features work, though. Running entirely "stock" shaders for now, probably need to tweak them a bit more for satisfaction.

standard_tree_v/f does not get shadows cast on it for some reason I guess I'll look into that.

 

[boomer541]

I set Splits=4, SplitsrenderJump all=0, and no changes to SplitsrenderOffsets and went from 80 fps to 62 fps on Carlswood with no flicker.

Graphics card GTX285.

This still needs work to get the fps back up!

 

[MitchVL]

The flickering is caused by the shadow mapping not moving per shadowmap-pixel in light space.
That's something that is not very high on the priority list, but since it seems to be disturbing, we should reconsider.

3 splits is enough detail
2 splits works great too if you dont mind a little less detail (set the split distances higher to cover more distance)

@AMGfan: looks really good! The shaders are actually working out too

thx mate, your update are really good
