disable VK_KHR_present_wait

[royal iris]

Hi iwant ask about how can i disable VK_KHR_present_wait on intel arc gpu mesa driver

[thorny lava]

huh? how do you want to disable it? as in stop the driver from exposing the extension? why?

present wait doesn't increase latency though? and besides - do games even try utilizing the extension?

having an extension exposed doesn't necessarily mean it's used - it's used only when enabled by applications

when in doubt it probably doesn't tbh

wdym?

present modes don't "use present wait"

VK_KHR_present_wait gives you an opportunity to wait until presentation of an image is guaranteed to be complete, and applications can use that for pacing purposes - it's not tied to any present mode

doing this should generally decrease latency, by the way, so disabling it probably wouldn't help you at all

how did you get the idea that VK_KHR_present_wait increases latency?

there are problems with it but I don't think that results in increased latency generally

if you really want to disable it you'd need to modify source code, but like I said it's not going to decrease your latency

it's a general vkd3d option so it should work on any gpu
