[Bug] Disabling Triple Buffering Causes Video Corruption on Linux with Vulkan

[TyranT⨁]

When disabling triple buffering in the video options, video corruption is present. Then it crashes after like 30 seconds. This is on Arch Linux with an NVIDIA card. Full specs are in my profile.

Vulkan is still in beta stages so it is likely to work like crap on most hardware. When you change triple buffering, try rebooting the game and see if it still happens.

Turn the steam overlay off. Serious engine + vulkan + steam overlay + nvidia = graphics corruption, crashes, lockups etc.

I have the Steam overlay disabled in all games, so that can't be the reason. I'm aware the Vulkan API for the Serious engine is still in beta, I was just letting the devs know that it exists. I personally don't use VSync in any games, so I have no use for triple buffering, hence why I disabled it. The game runs fine with it enabled, its just triple buffering makes your game feel more laggy, as well as VSync, hence why I disable them.

I always associated triple buffering with VSync and that it tries to minimize lag when using VSync, but when enabled with VSync disabled, it makes games feel more laggy, like a smoothing effect. similar to VSync. Double buffering always felt more responsive then triple buffering. I would like to test this once and for all if using double buffering under Vulkan was possible on Linux without it bugging out.

Makes no sense.

Well triple buffering will buffer an extra frame, so kind of similar to in the NVidia control panel, you can set an option to how many pre-render frames are drawn. The higher this value, the more input lag is present, but the game feels smoother. Some people can't even tell the difference between VSync on or off, let alone if there pre-rendered frames value is set to default (3), which feels laggy compared to someone who has it set to 0.

No, it's not the same thing and not even farly similar to that. Wikipedia tells you how it works. Pre-rendered frames are totally another planet.

Its similar to the fact it adds another frame to the render, whether it be buffered or actually rendered, it still adds another frame, hence the similarity in that aspect. I notice when I disable triple buffering, my cursor in the menu is more response, like how it feels on the desktop, as to when triple buffering is enabled, where my mouse feels floaty and smoothed. This is how triple buffering also felt to me.

That's a malfunctioning triple buffering. Triple buffering does not "add a frame", it "renders" 3 frames at the same time instead of 2. You still have 3+ "frames" with double buffering, you just render 2 instead of 3.

That's what I meant, but it sounded silly to say it renders another frame to the render lol
