Bug: Vertical Sync doesn't behave like Source.

[LittlePlanetCD]

Describe the bug

In the best, yet shortest description i can give of this:
Strata seems to have a problem in its DX11 renderer where VSync actually caps the framerate to the refresh rate, when in Source this very much behaves differently. Source still seems to try to render at high frames while somehow still maintaining a solid display with no tearing.

Strata, Momentum Mod:

Half-Life 2 (Anniversary Update):

To Reproduce

1. Open game (Example being momentum mod, my analysis was done on the steam playtest build, main branch). ensure DX11 is the renderer.
2. open any map
3. turn on vsync while having the fps display on
4. see that it caps to the refresh rate.

Issue Map

happens on any map.

Expected Behavior

Strata should be rendering like how source does on DX9 with vsync enabled.

Operating System

Windows 11 23H2

Vsync capping framerate is how it always worked in source (and everywhere else). Why it does not cap framerate in hl2 for you, might be because some driver hacks going on when it detects hl2. Or something is up with anniversary update.

You also did not specify your HW configuration (at least the GPU(s) since this is graphics related.

Even if this behaviour is not consistent, wouldn't it be better to keep it this way? Locking the framerate to the refresh rate is how vsync should work.

[SCell555]

Also to note that vsync does only work in exclusive fullscreen mode on dx9, while on dx11 it can work in borderless and windowed mode.

while on dx11 it can work in borderless and windowed mode.

i guess that makes sense, fair enough. sounds like intended behavior in this case
