Hello guys! We all know that tuning Skyrim is a mysterious and sometimes tedious ordeal, especially considering when there are tons of guides around and every single one usually seems to contradict the next. And that one says the total opposite of the one you read just the day before.
In the todays article, we want to share with you some *not so commonly discussed*, but very useful tweaks we took note of during the past fourteen months of RCRN development!
Bethesda released the “4gb patch” more than 8 months ago, but this doesn’t really matter, it was just a LAA fix in order to allow the properly handling of memory under 64 bit systems. But this doesn’t necessarily mean your system will automatically use more than 4gb of RAM!
In order to tell to Skyrim your correct amount of system memory you have to apply the following tweak:
Open your Skyrim.ini, usually located at the path: C:\Users\youruser\Documents\My Games\Skyrim and search for the line under the [Papyrus] section:
Then change the value marked as “*******” with the approximate amount of your system memory, by consulting the tab below:
if you have 4GB of ram -> iMaxAllocatedMemoryBytes=2000000000
if you have 6GB of ram -> iMaxAllocatedMemoryBytes=3000000000
if you have 8GB of ram -> iMaxAllocatedMemoryBytes=4000000000
(if the line is not there, simply add the appropriate line *only one choosing with your systems RAM amount)
This tweak usually helps really a lot, we found that the game is about 20% smoother when the properly memory value is set!
A lot of guides around the web advertise to keep this value to “0”, this is a common misconception. Advanced lighting mods like both RCRN and ENB actively use this settings and they require it set to “1”, keeping it disabled doesn’t provide any advantage, only issues. As can be seen in the example below:
The purpose of this setting is providing a more accurate lighting by using floating point verc’s/points instead of only int values.
In order to properly set this value, open your Skyrimprefs.ini, usually located at the path: C:\Users\youruser\Documents\My Games\Skyrim and set the following line:
Note: This fix is not useful with low tech CK only lighting mods, like cot or rlo/rlwc, because they cant play with float values!
In vanilla Skyrim there is an annoying issue that often makes light sources like braziers or torches looks dim unless you move near them, this is also known as the “lights pop-up” bug.
It’s mostly caused by an engine issue, but it can be easily avoided by setting:
in your Skyrim.ini under the [General] section!
When you are running a lighting mod that has his own screenshots management and uses the “stamp/print screen” key on your keyboard to take them (like RCRN for example), you will encounter a “screenshot duplication” containing a screenshot of the vanilla image. To eliminate the wasted clutter caused by the generation of a .bmp screenshot when creating the proper .png shot, make the following edit:
in your Skyrim.ini under the [Display] section, you will block the useless .bmp generation, keeping only the .png shots containing the RCRN effects of the on screenshot!
Along with every single Skyrim user, we have also fought versus those horribly blocky shadows.
After some tinkering we finally found a combination of settings that pleased us, here is what you have to edit in your SkyrimPrefs.ini:
in the screenshots below you can see our fixes in action:
Note: this fix also helps in reducing the “shadow striping” problem.
Additionaly we also took care of the “laggy” shadow timecycle, this 2 settings when added under the [DISPLAY] section of your Skyrim.ini will make the shadow transition much smoother!
Here we finished with our 5 cents, we hope that they can be useful to you and that they can enhance your gameplay and push it even further!
