MX Simulator

Changes:

• Terrain normals are now calculated in the fragment shader instead of being baked into the terrain normal map cache.
• Added "Terrain Sync Rate" setting.
• Removed update rate restriction when painting in editor.

The terrain sync rate controls how quickly the system memory height map is synced with the graphics memory height map. "0" is 64k per frame, "1" is 128k, "2" is 256k etc. Probably best to keep it set low since it'll still update plenty fast and you leave more bandwidth for other stuff that way, but even at 10 it shouldn't max out a PCIe 3 bus.

Replace mx.exe or mxbin with one of the above files. The default location for mx.exe should be "C:\Program Files (x86)\MX Simulator". Please note that the ".exe" extension is hidden in Windows so the file will just show as an application named "mx". I'd keep a backup of the originals since these aren't well tested.

okay so, what would be the most recommended setting for this?

New snapshot drops my frames by 50%. Changed all graphics settings to go for high fps, no change.

No problems with framedrops for me after testing on some outdoor demos. I have an intel i9 and an NVIDIA card so I can't say for people with AMD cpu's/cards but I haven't had any problems so far.

0 will work perfectly fine.

I could be mistaken but I think the newer snapshots (past 03-31) are still having issues on AMD cards.

So in dumbass terms what does this update do?

Updates the way erode changes to the track are stored into your computer. It removes the need for a reshade delay and instead syncs the terrain changes from the fragment shader to the graphics memory. Basically terrain sync rate is the rate at which the calculated erode changes to the terrain actually syncs to what you see on track. (I believe)

0 should be fine. Turn it up a step if you notice the shading isn't updating fast enough. In the worst case where the entire terrain is simultaneously modified, it would take 256 frames to update a 2049x2049 terrain at 0. If you set it to 8 it'll update that terrain in one frame. But doing the whole thing at once could cause a stutter, so it's up to you.

Is this vs the previous snapshot that switched to core OpenGL 3.1 or vs the older ones that used OpenGL 1.2+extensions? I know there's a performance problem with AMD cards on Windows with the new OpenGL code (i.e. since 2021-11-22). I was waiting on a new drive so I could install Windows on my AMD machine but I was already pretty deep into redoing the reshading code when it arrived. Going to investigate that now.

Faster reshading with erode or when editing.

I encourage everyone to go try painting a gradient in the editor

Didn't test this until now and it's sooo satisfyingly smooth

Sanday 3.0?

So satisfying ! Next step : Have the possibility to resize decals directly on the editor instead of :
1 - Open the decals file with notepad
2 - edit size
3 - reload the map
4 - check if the size is right, if not, go to 1.

Turn Vsync off in your GFX settings.
