This is a forum (low bandwidth and storage) and not a video hosting site (high bandwidth and storage), upload a video to any video hosting site and post a link.

What does this do? Does it not force software rasterization?

Steam client is a 32 bit application, and there is actually no 32 bit GPU driver on Orion O6, because its CPU is 64 bit only based on ARM V9. Here swrast is used as a workaround for launching steam client, but it won’t disable the GPU acceleration for Witcher 3 (64 bit), which is based on DXVK as shown in the pictures.
