Input lag

[Zortax]

Hi everyone, I have been facing an input delay problem on all games that i play on. i use a ps4 controller.
my pc is very decent in running games. and i have been also using the same ps4 controller to play steam games and i had no input delay on them there. 
so the problem is supposed to be from the emulator itself. 

can anyone help me with fixing this issue please? 

my specs: 

Processor AMD Ryzen 5 4600H with Radeon Graphics     
  3.00 GHz
Installed RAM 8.00 GB (7.37 GB usable)
Nividia GeForce GTX 1650
System type 64-bit operating system, x64-based processor

Known issue, hasn't been fully fixed yet.
But mtgs queue from latest Dev builds help a lot reducing input lag

I'm sorry but, what does mtgs queue mean? and how can i find that to help reduce the problem?

I've done that and tried playing. the input delay still didn't get any better.
are devs aware of this issue since it's very common with most users?

yes they are.
did you fiddle with mtgs queue setting ?

a little.

[jesalvein]

try to fiddle more.
It should really improve things (without solve them fully)

So how exactly does mtgs queue work? Does v-sync need to be on?

Default value is 2, does that mean increasing it will increase input lag?

Higher means more frames are allowed to be queued but not rendered, lower means fewer frames can be queued. Set to zero to force MTGS to never queue any; this will increase CPU requirements but force frames to be drawn immediately.
