    why ?

    I repeat - can we hear game name (or games list) which locks at 30fps ?

    usually it have effect especially if no scaling used and default/new dx11 renderer (in this case will be lower GPU load => more chances GPU drivers will think they are smart and clever, and will decrease GPU clock about to "2D profile" values => this lead to stuttering / slowdowns)

    Hey MetalliC, my main man, maybe comparing these 2 will help:

    Vsync OFF: LINK


    Vsync ON: LINK


    Is Vsync OFF supposed to be that stuttery? Just looking at the naomi and capcom logos scroll obviously shows it. With Vsync ON it's smooth, but people want to play it turned off because of the input lag.

    All games do this. Pretty much what kalawangman said with the whole vsync issue with arcade titles and input lag. Look as these vids and maybe you will believe us. I don't think the whole statement regarding the new dx renderer is true. If that were the case, then some slight slowdown would occur and I'm not getting any form of slowdown.

    mmkay, I think I get it.
    you are hijacked the thread and saying not about emulation slowdowns, stuttering or any kind of performance-related problem, but completely different issue: if VSync is disabled - visuals moving not smooth but kind of choppy.
    I think it will be better in next version.

    if speaking in general, "VSync makes (huge and notable) lag" is only certain game's engines design problem (Valve's Source Engine for example), and not takes place in 3D applications in general.
    I see no reasons why not use VSync in emulators, and how it may add any kind of input lag here.

    So, back on topic, sort of... I'm having issues too. Demul's only running at like, 19 fps on the bios. The new Dx11 plugin doesn't seem to work and the old one doesn't seem to notice that I've got a graphics card.

    Honestly, it's shocking that I'm even getting 19 FPS.

    Build: Ryzen 5 1600x
    16 GB DDR4 2400 ram
    1050 ti graphics card

    Edit: Updated graphics driver. Fixed problems. Oops.
