minor tearing with G-Sync
Posted: 15 Jun 2017, 16:37
Hi,
So, I've read the articles on G-Sync 101 (Introduction & Range) and am aware of the issues concerning framecaps too close to the refreshrate with G-Sync on and V-Sync off.
However, I can still sometimes see some minor tearing on the bottom half of my screen, even when capping significantly lower than the monitor rate (e.g. 80 fps cap vs. 144 Hz monitor rate) and having both G-Sync and V-Sync enabled.
It is particularly noticeable in Battlefield 1 and to a lesser extent in Witcher 3 (both using in-game capping). It seems to be mostly the case however when there is a lot going on or many assets being loaded in quickly. For example, when walking around in Witcher 3, I can't see any tearing at all, but when sprinting I do see some minor tearing now and again in the bottom of the screen (although you can only notice it when you really focus). When sprinting and looking at the sky, I can't see any tearing either, consistent with there being fewer assets.
Is this all indeed due to frametime spikes and thus unavoidable with GSync? In other words: do we have to allow for some tearing (however small) unless we only use VSync and just delay the whole frame?
Many thanks for any responses and with regards,
PM
