Fallout 4, shipping tomorrow, is built on the exact same engine as Skyrim and previous Fallout games. Anyone acquainted through Skyrim"s expandability with mods and .ini tweaking might recontact “iPresentInterval” – well, it"s earlier.

iPresentInterval isn"t just a V-Sync identical, which would lock the frameprice to the refresh rate; rather, iPresentInterval caps the frameprice at a hard 60 max (also through a 120Hz display). In Skyrim, altering this setting can influence physics events and was frequently recommended left on, despite the framerate limitation. To be fair, neither Skyrim nor Fallout are games that benefit from the notoriously high framerates demanded by CSGO players, for instance, however customers of high refresh rate monitors still want their FPS.

These actions will certainly deal with 2 Fallout 4 issues: A “laggy” mouse that resembles acceleration or smoopoint and also the locked 60FPS cap.

1. Launch Fallout 4 and also click “Options.”

2. Connumber the options to your liking. Cshed the food selection items and also click “Exit” to quit Fallout 4 entirely.

3. Navigate to My DocumentsMy GamesFallout4.

4. Create a backup of Fallout4Prefs.ini (copy/paste locally)

5. Right-click Fallout4Prefs.ini, click Properties, and also ensure that the file is not presently collection to read-just. This should just happen if you"ve been below prior to, otherwise it"s writable.

6. Edit the file. Ctrl+F for iPresentInterval.

7. Change iPresentInterval=1 to iPresentInterval=0.

8. Save & cshed the file.

9. Right-click Fallout4Prefs.ini, click Properties, and check the “Read Only” box, then use your settings.

Fallout 4 will certainly no much longer have the ability to modify game settings at startup, so you"ll must make the file writable aobtain (reverse step 9) in order to readjust resolution, shadows, or any various other settings. The purpose of locking the file is so that iPresentInterval is not reset, because Fallout 4 resets the file at each launch.

Tright here is a Fallout4Custom.ini, which we suspect is an override for some various other file. We tried adding iPresentInterval right here, yet it didn"t seem to take. Success was only completed via Fallout4Prefs.ini.

FPS have the right to currently exceed 60. As a side impact, the computer mouse should currently feel even more organic (like raw input) and also the lag / smoothing / acceleration impact have to dissipate with greater frameprices.

In Skyrim, it used to be the instance that including bMouseSmoothing=0 to the block in .ini documents would certainly remove smoopoint, yet we"ve been using the above solution rather for Fallout. If you discover something that functions – and most things that functioned in Skyrim & New Vegas have to job-related here – short article it listed below to aid the others that land on this page.

Steve began ago as soon as it was just a cool name, and now it"s grvery own right into an expansive website via an overwhelming amount of functions. He recalls his initially challenging decision through GN"s direction: "I didn"t understand whether or not I wanted "Gamers" to have actually a possessive apostrophe -- I mean, grammatically it have to, but I didn"t prefer it in the name. It was ugly. I also had actually civilization who were inputting apostrophes into the address bar - sigh. It made feeling to simply leave it as "Gamers.""
