Program freezing

[mclarekin]

See if these settings freeze program in openCL (infinite calculation??) . I need to end task to get out.

confirmed freeze, this require me to pull the power plug after disabling TDR! @buddhi1980 please investigate

These settings even on CPU are extremely slow. 4 hours to render at resolution 800x600! It't not infinite calculation but VERY long.

[buddhi1980]

aux_light_volumetric_enabled_1 true causes the problem. If you disable volumetric light then rendering speed is quite normal.

[buddhi1980]

By the way optimal raymarching step multiplier is 30 for these settings! With DE_factor 0.7 it was very slow without improving quality.

the way optimal raymarching step multiplier is 30. wow! that is interesting!
