Hi. I have rzyen 5600h cpu and 32 gb ram nvidai gtx pc configuration
for examle I have 900 photo totol data is 8.5 gb
when I start alling photos procces time is 3 hours
but another software (agisoft) this is 1 hour
how can decrease procces time in 3d survey and why procces time more than another.?
thanks...

Well, 3Dsurvey is a survey tool, so the software focuses on accuracy rather than process speed, as it is immensely important. You can speed up the process by setting fewer tie points, but the result will be less accurate.
