Hi everyone ! The “Super NT” announcement made me think about hassling you again with this dreaded input lag subject Sorry about that
I created a new bounty suggestion for a Lakka build with Nvidia proprietary drivers + a proper use of the Vulkan X-free context (or Nvidia KMS).
Did anyone here measure the input lag difference between some common Linux setups like -
- X + OpenGL
- X + Vulkan
- Vulkan X-free context
My experiments : under both Arch & Ubuntu, with a current Nvidia gpu, Vulkan “almost works”. It does work under X but I’m not sure if I’m supposed to benefit from a reduced lag under X (is double buffer applied ?). Vulkan X-free context ALMOST works. Actually, I can start retroarch from the console, it works. Well, if I specify a game from the command line the game works. If I don’t, the menu works, but I get an error if I try to start a game from there (resource not free or something). The Nvidia KMS mode segfaults.
Well, all that is promising Sorry for annoying you guys !
