slow lights on rtx 3070 mobile, cant run the game on native resolution

[sam8109]

lights after bouncing off the surfaces are slow (specially on weapons and after turning off the flashlight, or any detailed reflection). It takes a lot of time to update the reflections.
If you stay still it's good

But since this game has lots of moving, most of the time it looks like this

And the other problem is I can't set the resolution to my native resolution (native is 2560.1600, max res in game is 1707.1067, and it's borderless)
Is there any fix?

This is likely because you're using a hiDPI display, and the executable is not marked as DPI-aware.

To fix this, close the game, right-click the Serious Sam RT executable, go to Properties > Compatibility and force the scaling mode to Application.

Note that for a full raytraced game, rendering at 2560×1600 on a RTX 3070 Mobile is a tall order (for targeting 60 FPS). I'd probably stick to 1920×1200 at most.

In general, rendering at higher FPS will help light bounces converge faster (as long as framerate isn't capped via other means such as V-Sync). This is also where decreasing the resolution can help.

Thanks for help, but my main problem is the slow light bounce. in order to fix I have to get around 400 fps (only achievable on 640x480 or lower). and dlss causes white bars around screen and blooms into game. the game is somehow unplayable for me.
Edit: Such a problem does not exist in versions older than 1.5 (1.4 is not available for download)
Edit: for performance, 2560x1600 is not a problem if you enable dlss (I get around 85 fps with dlss set to performance mode)

I have the same problem with slow lights.
Has anybody found a solution?

There is a commit in RayTracedGL1 that hints at a fix for this issue. It was made one day before the release of 1.5, so I don't know if it's already included in that release.

There's a fork with a newer version of RayTracedGL1 that is compatible with Serious Sam RT: https://github.com/plzombie/RayTracedGL1_serious_engine/releases/tag/v1.1.0-patch1

Thanks, but I can't enable DLSS with this fork :)
