Thank you for your patience and your time.
I’m late replying due to a funeral far from my city
I understand that from a distance, without knowing the real state of the PC, therefore of the hardware and software, one can only make generic hypotheses and suggestions.
Regarding your answer, I would like to inform you that today I downloaded and installed the latest nVidia drivers for the MSI GeForce RTX 4080 16GB Gaming X Trio.
I had already abandoned Brave stock to use the Beta version as recommended above and it seems (the conditional is a must) that there are no longer any delays in opening the pages - moreover even with the presence of 3 of the 4 plugins that I don’t want give up: they generally open instantly except for understandable server slowdowns which do not indicate browser malfunction.
So I’ll stay with the beta for a while, then I’ll see if I should go back to the standard version.
We can close here.
Good things…
