Ticket #180 (closed defect: fixed)
Default DepthTextureBits is very slow on GF4
|Reported by:||Philip||Owned by:|
By default, the shadow DepthTextureBits is 16. With a GF4, that is very slow compared to other depths - e.g. on a blank grass map, with AA disabled, it is 72fps with DepthTextureBits=32 and 23fps with DepthTextureBits=16. With 4xAA enabled, it is 36fps at 32, but only 2fps at 16.
Is a similar effect visible on other graphics cards? (Use renderer.depthTextureBits in the console to change it). If so, presumably the default should be changed; otherwise, the default should depend on the hardware.
