Jittery vsync

Love this port. I have a problem where turning on vsync creates a jittery framerate that seems to skip several frames at a time. I've tried all video settings and framerate caps and they all seem to exhibit the same problem.

And I can't seem to force a smooth framerate using external limiters or NVIDIA control panel settings, either. No vsync and it's fine but the screen tearing can be pretty bad.

i would recommend using the ingame framerate limiter and then use borderless program to get it to run in proper windowed fullscreen,

Runs like a dream when i do this.

Devon, what is your screen refresh rate and what limit did you set?

For some reason I get screen tearing with or without borderless windowed or fullscreen. The frame limiter only causes tears to happen at different frequencies.

Don't know how helpful it is, but most of my problems seemed to be alleviated by running the game borderless AND running it at a sub-desktop resolution. So running it in 1600x900, where my desktop is visible beneath the game window, seems to fix 90% of the stutters I was experiencing.

I also set up as second monitor the day before trying this, but I don't know what effect that might have if any.

60hz screen.

And i have fps limit set to off.

Also i dont use bloodgdx borderless option as it does not work for me. i have to use the borderless gaming program instead.

Try asking Zaxx; I hear he is a big fan of BloodGDX and an expert on V-SYNC.

Can you try this version?

Devon
Borderless mode should looks like on the screenshot. Are you have other?
