Best way to convert lighting to ShadowMap?

I have this game that I am currently working on utilizing Future lighting (picture below)

But, I realized that on lower end devices, (phones, potato pcs, bathtubs) the performance would tank all the way down to 30 fps

The only way I decided to avoid this issue is to change the lighting technology to ShadowMap and…

woah

I honestly thought it would look a lot better considering all of the SurfaceLights, but I guess not
If there’s a way I can make ShadowMap look almost as good as Future lighting, I would appreciate your response.

Looks like the 2nd image is using voxel and not shadowmap. What are your lighting settings?

Both Shadowmap and Voxel look the same

Future is only enabled when the graphics setting goes above 4 (At even at 4, the range for future is TINY)

But, because of this, players on bad computers will easily be able to run the game, because if they’re on a bad computer, why would they be playing at higher graphics settings? Future would just be disabled (Or have a very small range) for them.

And, so you can see, here is future at different graphics levels on one of my games.

(And yes, I’m remaking FNaF 2 for fun, but am adding my own twists to it)

But anyway, there isn’t really any way to “Make shadowmap look like future” because they’re entirely different light rendering systems.

I should have been more specific

When testing my game on a mobile device, I noticed that setting the graphics above 2 tanks FPS down to no higher than 30, even though future is enabled at 4. What I am trying to do is make Shadowmap look as similar as future, without the performance issues from lighting

There also isn’t really a way to check graphics quality, too I think.
So if you do find a way to make shadowmap look good and “like future” then it’ll probably just look bad on future. Just deal with the low graphics settings, there isn’t anything you can do.
