The Witcher 3 game may have brightness problems when running on some systems. In the dungeons it can be too dark, or vice versa — the brightness in some locations can be very high. There are a few simple ways to fix this issue.
What is the "ERR_TOO_MANY_REDIRECTS" Error The ERR_TOO_MANY_REDIRECTS issue ("Cyclic redirection on the page") or "redirect loop" occurs when the server alternately redirects the client to different addresses, the last of which redirects to the first address, thus creating an endless loop of redirects. Most often, the cycle does not contain a large number of addresses - usually these are 2 addresses that redirect the client to each other, for example https://www.example.com -> redirect -> https://example.com -> redirect -> https://www.example.com and so on ad infinitum.
