xREL.v3

General Performance
Graphics settings have been tweaked to improve performance. We have also fixed a bug that would change some settings upon loading after the initial run.

SLI performance
We have identified an issue with NVIDIA SLI setups related to cloth meshes in the game, which were causing GPU stalls during geometry updates. This is now fixed.

21:9 Ultra-wide resolutions
We have now added support for ultra-wide 21:9 monitors.

Field of view
We have added a command line variable which allows the default field of view to be changed. To do this, edit the following line in the 'system.cfg' file, located in the root of the install folder (by default: C:\Program Files (x86)\Steam\steamapps\common\Rapture\):

Cl_fov=X

(where ‘X' is a value between 25 and 80)

Please note that the game was designed with a default FOV of 52, and changing this setting may cause some minor clipping issues within the environment.

Main GPU vs. integrated GPU detection
Some users have reported an issue with the game defaulting to their integrated GPU, rather than their main (more powerful) GPU. We have added a command line variable which provides an alternate detection method, which may help these users. To enable it, please edit the following line in the 'system.cfg' file located in the root of the install folder:

r_overrideDXGIAdapter=X

(off by default = '-1'; try setting value to '0', '1' or '2' to cycle through available GPUs)


Crash on triggering scenes
A small number of players have reported Microsoft Visual C++ related crashes upon tuning some of the manually-activated scenes. We have been unable to reproduce this issue internally, but have implemented a tentative fix by including additional dll’s in the game install.

Windows System Timer
In rare instances, the game may run slower if the Windows System Timer defaults to low resolution. To force the game to enable a high-resolution timer (and potentially improve performance), please edit the following line in the 'system.cfg' file (located in the root of the install folder):

sys_highrestimer=1

Manual save points
Separate to this patch, we have also implemented a new "beta" feature that allows players to manually save at every framed map in the game world. Please note that this is a big change to the game, which wasn't designed with this feature in mind. Whilst we have tested it internally without any observed issues, your mileage may vary.

Since this is a "beta" feature, it is only available by opting in to the "beta" branch of the game on Steam. To access it:
In your Steam Library, right-click on "Everybody's Gone to the Rapture"
Select "Properties"
In the Properties window, click on the "BETAS" tab
Under "Select the beta you would like to opt into:", select "map_save"
Click on the "CLOSE" button at the bottom of the window. Steam will then download an update for the game.


Please note that the manual save system will not be available:
while a scene is playing, or for up to 20 seconds after the end of a scene
if you are in the vicinity of a manually-activated scene (even if said scene isn't currently playing)
during time-of-day transitions between chapters

In case you encounter an issue with any of your save files, it's possible to revert to a previous save by doing the following:
Navigate to your save folder: C:\Users\<USERNAME>\Saved Games\Rapture\SaveGames
Delete the two most recent files in the folder (or move them to a different folder if you want to keep them): one has the *.csf extension, the other the *.meta extension.
Start the game again and select "Continue" – the game should load in the penultimate save location.
