Ray tracing not ready yet?

[SatanSoldier]

Geforce experience, nvidia drivers, and derail valley are all up to date but alt-F3 isnt bringing up a sidebar. Geforce Exp isn't showing Derail Valley as a Freestyle game and it isn't on the supported games list. Am I missing something or is this feature not actually going to available until the next nvidia update?

Try manually checking for GeForce Experience (not just GPU driver) updates. I've had my application fail to fetch updates a few times. Assuming the app and drivers are up to date, a simple system reboot might be what's needed.

When you get it working I'd really appreciate it if you could take a few minutes to share some screenshots with it enabled.

Did you enable the experimental functions in General settings of Geforce Experience app (screw icon, upper right corner)?

[SatanSoldier]

I verified that Geforce Experience is up to date, so are the drivers. Tried enabling experimental and rebooting my PC. Still isn't working.
Has anyone actually got it to work?

Yes it works for me but on my RTX 2080 Super (without experimental), I get 20fps instead of 40 in Harbour town.
And the visible effect is minimal. Not worth it.

Are you shure that Geforce Experience is running in the background ? Can you access the Nvidia Overlay with STRG Z (for the German version)?

I had to check the experimental option before it showed up.

Make sure you have the in-game overlay turned on in GFE. You should be able to press Alt+Z to bring up the menu, Alt+R for performance metrics, etc.

I had to reinstall GeForce Experience despite already being on the latest version.

It works for me, but is hardly worth it for the frame rate loss tbh. Goes from 90fps to 60fps on my 3080ti.

You need:
- latest GF experience
- latest GF drivers (update to very latest game-ready ones)
- enable experimental updates in GFE
- enable overlay in GFE

Once you have the above you can press ALT+F3 in-game and find the overlay. If it still isn't working, you may have an overlay conflict with other programs. Try to find everything else you are running that has an overlay (Steam, Discord, NZXT CAM, etc.) and disable all of these then try again.

After you get it working, then in-game you have to select the SSRTGI in the menu on the left, and...

MAKE SURE YOU ENABLE BOTH "invert Depth Z-axis" AND "Invert Depth Y-axis"! Otherwise you get some weird looking upside-down tree artifacts LOL

I tried putting the filters in and it rendered all the reflections upside down

[SatanSoldier]

OK, there it is. The overlay being enable is apparently what I was missing. It is a nice improvement but it does reduce FPS buy 10-15 on a 3090.

A FIX for inverted upside-down artifacts:
After you add SSRTGI filter, click the down arrow next to it to open details for the filter, and MAKE SURE YOU ENABLE BOTH "invert Depth Z-axis" AND "Invert Depth Y-axis"!
Thanks @Vandragorax.

Drops my fps to 55 on 4k max settings, unplayable

The filter seems to be hit or miss on my system. Depending on what direction I'm facing it turns on and off. Running on a 4080 @ 2560x1440. Spanning across 3 screen breaks it even worse but I was not expecting it to work on more than the primary screen anyways. Good first attempt though!

Does the "ray tracing" create accurate shadows in the cabs of locos as they pass under lights in the train yards? That's all I really want out of it, but if that's not a thing, then I'm not going to bother.
