One quick question if someone can help answer.

With the RTX cards we should be able to preview lightmap baking or so I understood from the Gameworks Ray Tracing Demo but will we still need to bake the lightmaps on CPU or will the GPU do that? We might end up with different results then seen in the preview if the CPU does the lightmap baking, right?

I need to know if it’s worth investing in a good CPU worth £1000 or just wait for 4.22 to come and just get an RTX card which I’ll do anyways.

Thanks.
