>>> What CPU do you have?

>> Intel(R) Core(TM) i5 CPU       M 540  @ 2.53GHz
>>
>> That is two cores, and I have enabled hyperthreading.
>>
>>>
>>> On Raytracing, complex boards will take about 10seconds per CPU core just for rendering, it means if you have more cores it should take less. (depending also on the resolution)

>>> Regarding the load times, I was expecting the same or faster (it should be faster in the future even more).

>>> (I believe you mean solder mask ?)

>> On a second though, I mean solder paste and solder mask actually. :)

>>> Since I received lots of requests (you and Maurice :P)
>>> I implemented that feature (on solder mask) in my latest commit.

>>> I was not very clear on if / how should I implemented the holes of the vias.
>>
>> The old viewer shows holes in the solder make and paste at least.
>>
>>> Since there is no information to remove solder mask, that in the fab. will be "tented" vias.
>>> I leave it as discussion.Maybe I can add an option to remove it or not... but at moment it is by default implemented.
>>>
>>> There is an issue with that.. this is only work (at moment?) with THT vias.
>>> So it will not remove if it is a "micro via" between B_Cu/F_Cu and a inner layer.
>>
>> I am not too concerned about the microvias, personally. My concern was
>> only on though hole pads such and the normal vias.
>>
>> I see your implementaiton of the holes in the mask now. But it looks
