Thank you for pointing that out. But you do not need to use large fonts, normal fonts would suffice.
The fact remains that the result of the Proline test is consistent with other reviews such as the one here, which is not limited to 10s:
The difference being the above does not test 4K, only 1080p and 1440p. Also EGLL. Duration : 2mn46.
My suggestion is to use a baseline for comparison, if you have another one in mind, feel free to share. OP is running the sim in 4K.
Also I fail to grasp how the duration is relevant when we are just trying to assess whether the same result can be achieved, in the same conditions.
Hope it works
