my game is lag so bad how fix this?
Are you sure another software isn't slowing down your PC? Your specs should be overkill. My old laptop with a dual core CPU and 4GB of RAM runs it perfectly. I can make a Vulkan build if you'd like, but it seems unnecessary. I would check and see if there's any antivirus conflicting with it, along with checking your GPU settings to see if there's any settings that could be causing issues. I know VSync does this for some games on specific monitors.
Let me know if anything changes, if not I'll publish a Vulkan build.
