Skyrim is an incredibly popular open world RPG that’s been ported to many different platforms. If you’ve played this game, you know all too well how taxing it can be on your PC when you’re trying to play.  Modern PCs can easily handle Skyrim, and new “next-gen” consoles are more powerful than ever, so why can’t you play Skyrim at an acceptable framerate?  This is a problem that can be solved with mods, and TESV Acceleration Layer is one of the most popular mods for Skyrim that does just that.

Skyrim is a huge game, and getting the most of your gameplay experience is guaranteed. However, if you’re using a system from the past few years, then you can probably expect to spend some time waiting for the game to load, which is especially frustrating if you’re playing a game that loads in the background. In this post, we’ll show you how to speed up Skyrim by 20% with a special mod that you can get from here. This FPS mod is also fully compatible with any other mod that doesn’t modify TESV’s source files.

This mod will increase the frame rate of the game by removing unnecessary lag from the game engine. It is very easy to install and will take only a few minutes to do.

Arisu and others created the TESV Acceleration Layer Skyrim mod.

A Skyrim Script Extender (SKSE) plugin to boost FPS (frames per second) in CPU-intensive sections of the game.

Users have reported an increase of 8-10 frames per second on average; others have reported a decrease of 2-4 frames per second, while others have claimed a decrease of 20 frames per second on average.

Download: Note: TESV Acceleration has been discontinued, the below link is to another Skyrim performance mod. Please accept our apology. Download from SkyrimNexus Requirements Skyrim (version 1.3.10 released 12/21/2011) SKSE (version 1.4.2 released 12/21/2011) Installation Instructions Install SKSE (Skyrim Script Extender) latest version from http://skse.silverlock.org/. SKSE must be installed to the same folder as Skyrim’s executable (TESV.exe). Install this mod, TESV Acceleration Layer, through Nexus Mod Manager, or manually to <Skyrim root>DataSKSEPlugins. Create the SKSE and Plugins folders if they don’t exist. Launch Skyrim using skse_loader.exe from the SKSE install. How does it work? From ianpatt (a SKSE developer): It replaces many calls to functions that would have been inlined if the compiler optimizer settings were set to something higher than “off” with actual inline code that nicely fits in the five bytes the jump instruction was previously taking up. It also overwrites several functions, replacing them with SSE implementations instead of the very painfully slow original x87 implementations. How can I tell if it’s running? First, make sure SKSE is running: Open the console in-game with the ~ key (above the Tab key), Then type in GetSKSEVersion and press enter. It should display the SKSE version in the console. If it doesn’t, SKSE is not running, and neither is the TESV Acceleration Layer, so you need to check your SKSE installation. Also make sure Steam is running before launching the game, and be sure to launch the game via SKSE_loader.exe SKSE is running? Good. Next step: Open skse.log (in the root of the Skyrim folder, with TESV.exe, skse_loader.exe, etc) In the log, you should see something like this: checking plugin G://STEAMS/teamApps/common/skyrim/Data/SKSE/Plugins/TESVAL.dll plugin G://STEAM/SteamApps/common/skyrim/Data/SKSE/Plugins/TESVAL.dll (00000001 TESVAL 00000001) loaded correctly TESVAL.dll is the mod. If you don’t see that, then it didn’t load correctly. Make sure your directories (folders) are correct. How can I tell if my game is actually running faster? First, be aware that FPS increases only occur in certain places where the game is CPU bound. Go to the top step in Whiterun and look down at the barren tree on the left. Try it with and without the TESV Acceleration Layer plugin installed. You will need an external program or plugin to check FPS (frames per second). There are several ways to do this. Here are a few options: FRAPS video recording program has an FPS overlay, even when not recording. The MemInfo SKSE plugin by Elys has an FPS overlay as well as Memory usage info. A couple of people have reported a slight decrease while using the Meminfo plugin. Known Issues This does not work with Windows 8 Beta. Those testing the Windows 8 beta need to report this to Microsoft.
