Delayed controls

[pikachu1001000]

On Nvidia 3070, the mouse controls and player movements are delayed when the ray tracing is enabled. However, if I switch to the Vulkan API, disabling the ray tracing, they are no longer delayed.

Apparently, the input controls are bound to the framerate, specifically in Serious Sam Classic. With Vulkan renderer, the V-sync is disabled by default, so most likely the game runs in 300FPS, so the delay isn't significant. With RT renderer, V-sync is enabled by default => FPS is bound to 60 (or other monitor refresh rate), and controls are less responsive.

The only suggestion is to enable Options -> Players and Controls -> Sharp turning.
Disabling Vertical syncronization might also help, but it will require more ray traced frames to be processed per second, which will cause GPU heating.

I have the same issue. Can't you setting in vulkan the pre rendered frames? There is same kind of option as far I know, in vulkan api the developer can control the pre rendered frames count. NVIDIA's control panel's ultra latency mode do nothing. :( This Sharp turning helped a lot, thank you. But still not so great I think I can't play in fullhd with rtx 2060 super.

Yes, it's truly uncomfortable to play with such delay. Sadly I don't have time (and PC) to fix it now. I really hope someone will investigate the possible solutions. Sorry :(

This cant be intended functionality. It is totally unplayable. My sensitivity is at 0% and it has input lag like I have never seen before.

Sharp tuning = yes
Mouse acceleration = no
Sensitivity = 0%
DLSS = Quality (to get 75-100 fps)

My settings for comfortable gameplay.

You are making sure that the gpu is not maxing out right?

Out of curiosity, can you reproduce this with fullscreen disabled and/or a FPS cap set (sam_iMaxFPSActive = 60 in console)?
