Initial impression - I have Vulkan on XPlane 11 since that was introduced to the sim and have been most impressed with that.
So - now smoother, good frame rates, much less tile load stutters.
The only possible downside, which might be another change you have made, is that the shaders appear to have become more 'contrasty'?
Train colours in low light times very dark with whites very bright. If you haven’t changed the shaders, I will look for an alternative on the website. I did previously find that steam locomotives were very dark.
Apart from the - great work thanks! Look forward to maybe being able to run at a higher screen resolution than the monitor as I did previously? I was running 2880x1800 on my 1920 x 1200 Dell monitor.
