/me agrees violently
btw., when i played with this tunable under -rt:
enum {
NV_OPTIMIZATION_MODE_THROUGHPUT,
NV_OPTIMIZATION_MODE_CPU
};
static int optimization_mode = NV_OPTIMIZATION_MODE_THROUGHPUT;
the MODE_CPU one gave (much) _higher_ bandwidth. The queueing model in
forcedeth seemed to be not that robust and i think a single queueing
model should be adopted instead of this tunable. (which i think just hid
some bug/dependency) But i never got to the bottom of it so it's just
the impression i got.
