Bethesda's Fallout 4 has just received its first official patch for PC. Bethesda is aiming to release Fallout 4 Patch 1.2 for PS4 and Xbox One owners, later this week.

　　After some beta patches for the PC version of the game, Fallout 4 has now received its first official patch. Developer Bethesda is hoping to release the patch for the console versions of the game this week.

　　Performance improvements inside the Corvega Assembly Plant

　　Optimizations to skinned decal rendering

　　Fixed issue with player becoming stuck in terminals

　　Fixed issue where equipped weapons become locked after completing Reunions

　　Fixed issue with "When Freedom Calls" where the quest would not complete

　　During "Confidence Man" fixed issue where player's health would continuously regenerate

　　Fixed crash related to jumping into water and reloading saved games

　　Fixed issue where Launcher would not save God Rays Quality setting properly (PC)

　　One of the more interesting fixes are the memory and stability improvements that Bethesda claims to have implemented with the patch. As noted by Digital Foundry, Fallout 4 seems to be heavily influenced by system memory speed.

　　If sustaining 60fps is proving challenging, we have some advice for you: consider faster RAM. We ran through a series of traversal sequences using a Core i5 4690K paired with a Titan X running at 1080p – in short, a scenario designed to remove the GPU as a bottleneck and stress the CPU. We then re-ran the test with faster memory. Below you’ll find our lowest and average frame-rate results from three different configurations:

　　1600MHz: 36.0/54.6

　　2133MHz: 39.0/61.0

　　2400MHz: 44.0/66.9

　　That’s a 22 per cent increase in performance with faster RAM comparing the slowest to the fastest. Now, this scenario is an exaggeration as the GPU is a major limiting factor in performance and by using a Titan X at a low resolution, we have removed that bottleneck. So are there any real-life applications?

　　Well, click on the shot above to see that – yes – faster RAM can make a difference in general gameplay, even with Fallout 4’s v-sync cap, and without an outlandish lack of balance in system components. Essentially, when the CPU is the bottleneck, faster RAM can provide an often dramatic increase in performance. However, before considering an upgrade, make sure your motherboard is compatible with faster memory. Usually this functionality is reserved for the top-end chipsets.

　　Lets hope this first patch improves overall performance of the game.
