8 GB of memory is not always enough
The PC version of Horizon Zero Dawn offers some really detailed textures. However, the chic surfaces also require a lot of memory. 8 GB is not always enough. For 1,920 × 1,080 and 2,560 × 1,440 it doesn't have to be more than 8,192 MB, but for 3,840 × 2,160 it does. Radeon graphics cards have more difficulties with the maximum texture details in Ultra HD than their GeForce counterparts, but the latter also get stuck every now and then. Horizon Zero Dawn remains playable on a GeForce, but the texture details should be reduced. A Radeon gets stuck again. Full texture details run flawlessly in Ultra HD from 11 GB.
In the case of graphics cards with only 4 GB, the full texture details should not be used in Full HD either. The combination is not unplayable, but it always gets stuck. Full HD runs from 6 GB without this restriction. For WQHD this only applies to a limited extent, with a 6 GB card there is occasional stuttering, again more on a Radeon than on a GeForce. From 8 GB, full texture details are no longer a problem in WQHD.

Now look at the jump for next gen - who really believes 10 GB is enough?
