We have changed the specifications of this MOD. Previously, you accessed the MOD's UI with the F8 key, but starting with this update, you can now open the Pause Menu with the ESC key and launch the UI from there. Additionally, due to changes in the base system, many of the bugs that occurred previously have been reduced. Thank you. ** !!!!!!!!!!!!!!!CAUTION!!!!!!!!!!!!!!!!!!!! We sincerely apologize for the delayed response. Regarding the MOD “Ultimate Optimizer and Compressor for Ark: Survival Ascended,” it stopped functioning due to an update to Ark’s base system. Since the last MOD update, my PC environment had changed, making it impossible to even check the current status. Thank you for your patience. As of 2025/11/21, the update has been completed!! We appreciate your continued support. **

NOTICE

When updating this MOD, it is recommended that you first upload your character using an obelisk or similar method, and also back up all your files before proceeding with the update. This can help prevent issues such as character disappearance, so please give it a try.

–WARNING–

As additional information: The previous F1/F2 gamma switching feature has been removed, since the official game now supports gamma adjustments working properly without modification.

–To Japanese Users– We have identified several bugs that occur only in the Japanese language environment, and resolving them has been challenging. One of these is a mysterious bug that appears for a few seconds to a few minutes when displaying the UI with the Esc key during debugging. After careful consideration, we have determined that it is nearly impossible to fix this issue within our MOD. As a workaround, installing and applying Google Keyboard has resolved this bug in my development environment. We would appreciate it if users could try this workaround on their end.

Because the official tools become unstable with each update, issues may continue to occur from time to time, but we truly appreciate your continued support.
