What your iGPU is? We'll definitely try to make it run on a wider range of hardware post-jam, but as mentioned by my colleague, we had no prior experience with this engine, so we failed to include graphics quality options. I guess on lower end machines we can use reflection planes and forward shading, instead of SSR and deferred shading.
There's definitely something wrong with engine settings as we've seen poor performance (<30 fps) on 2070Super if it runs a 4k monitor. It shouldn't be that bad, as SSR shouldn't be that expensive per pixel, possibly there's some engine settings which scale badly with resolution. We'll figure it out post jam :)
