Uh, if so, PLEASE add some option to turn it off in the launcher or something. My game is essentially unplayable with shadows on
For people playing at 1280x760 at the best, 2048x2048 is quite huge even though it's untextured scene, especially since it might be rendered more than once.
I think to reduce the load on lower system following quite easy countermeasures may be deployed :
#Option to lower shadowmap resolution, d'oh!
#Option to lower amounts of light casting shadows (people might be ok with just sun doing it)
#Option to lower LODs for depth test scene, would greatly reduce accuracy of shadowing, but should also relieve low ends system greatly due to great difference of detail on zero and first LOD models
Considering 512x512 scene just from sun, with one LOD up, you would get pixelizated edges on shadows, many minor details would fail to cast shadows, but performance impact would be absolutely minimal, and the effect should be good enough to hide small ships behind capitals, or to make ships like Hecate appear correctly.
Since Valathil provided a patch file, I'll mess it up when I get some time. I've got some older hardware to test how it on it anyway.
