@Joaquin Please see here Which graphics card do you use with Photolab? - #23 by BHAYT for some tests that I have run recently.
I have some updates which I will post but I purchased a RTX 3060 yesterday which I might be able to fit today or Thursday and when fitted and tested I will add the details to my post.
I “argued” with myself between an RTX 2060 for about £260 (as fitted to my Grandson’s machine but with a better processor and motherboard on his machine) or an RTX 3060 for £330, which was delivered this morning, in the hope that it might be a little faster!?
