Optiscaler Client: baixar versions anteriors

What's Changed
This update brings several bug fixes, including improvements to manually added games, profile parameters, FSR 4 INT8 on RDNA2, and NukemFG detection. It also adds a new Check for Updates option and clarifies app profile behavior. Finally, a known FSR 4.1.1 RDNA2 driver regression is documented, with 4.0.2c recommended as a workaround.

Changelog

Fixes
- Fixed a bug where the remove game icon disappeared for games that had been previously added manually.
- Fixed a bug where manually added games were no longer recognized as such after an update.
- Fixed a bug where modifying a non-existing parameter in a profile would not add it to the profile.
- Fixed a bug where, after updating the client from 1.0.5 to 1.0.6, games would no longer launch on RDNA2 GPUs using FSR4 INT8 4.0.2c.
- Fixed a bug where NukemFG (DLSSG-to-FSR3) was automatically enabled even in games without native DLSS Frame Generation support, causing OptiScaler to prompt the user to "enable Frame Generation" for an option the game does not actually have.

New
- Added a Check for Updates button under Help to manually check for a new version.
- Clarified that app profiles are custom .ini files.

Known Issues
- FSR4 INT8 4.1.1 may cause black screens, ghosting, or stuttering on RDNA2 GPUs (Radeon RX 6000 and APUs based on this architecture). This is an AMD driver regression, not a bug in this app or OptiScaler, and there is currently no ETA for a fix from AMD. Workaround: Use FSR4 INT8 version 4.0.2c instead of 4.1.1 on RDNA2 GPUs.

What’s Changed
This update introduces Linux support (tested on Ubuntu, CachyOS, and Bazzite) featuring a dedicated GPU detection system and Steam runtime optimizations. A new Custom Version Management system has been implemented, allowing the use of personal OptiScaler, FakeNVAPI, and NukemFG builds. Additionally, FSR 4 INT 8 is now automatically selected based on GPU architecture, and the update includes advanced library filters and an anti-cheat warning system.
Changelog
Added
- Linux Platform Support
- Compatibility has been added for Ubuntu, CachyOS, and Bazzite.
- A GPU detection base for Linux was implemented using sysfs and system tools (by @RafaelHGOliveira).
- Game scanning logic was adapted for Steam and custom sources on Linux (by @RafaelHGOliveira).
- Important exclusions regarding Proton and the Steam runtime were added (by @RafaelHGOliveira).
- GPU family detection by ID was implemented to correctly display the model in the main window.
- Custom Version Management
- Support for adding and managing personal or custom versions of OptiScaler, FakeNVAPI, and NukemFG was added.
- Custom versions now appear under a dedicated "Custom" tab in the game management window.
- Any version can now be set as the system default through the version management menu.
- Advanced Scanning Filters
- New filters in the scanning window allow toggling between three modes:
1. Scan All: Includes games where compatible upscaler DLLs are not detected.
2. Hide Non-Upscalers: Scans all sources but hides games without detected upscalers.
3. Strict Scan: Only shows games containing upscaler DLLs (experimental).
- Folder Cleanup Tool
- A "Clean Folder" option was added to the game management window to remove corrupt files or residues from previous installations.
- Safety & Information
- Anti-cheat Warning: Alerts were added for games where installing OptiScaler may cause issues (by @Louloubiwan).
- Welcome Screen: A one-time introduction screen with platform-specific information was implemented.
- Help & FAQ: Added instructions for Linux FSR 4 detection and folder recovery procedures.
- Network Connectivity
- A Proxy Configuration option was added to the Settings tab.
Improvements
- Smart Architecture Logic
- FSR 4 INT 8 is now selected by default when a non-RDNA 4 AMD GPU is detected.
- UI/UX Enhancements
- The OptiScaler version selector is now divided into three tabs: Stable, Beta, and Custom.
- The icon library was standardized for consistency between Linux and Windows.
- DLL version mapping was implemented for DLSS, XeSS, and FSR to show traditional version numbers.
- FakeNVAPI and NukemFG are now presented as selectors in the game management window for easier access.
- Custom sources are now included in the scanning menu of the Games tab.
- Process Optimization
- GitHub API request handling was improved to prevent recurrent 403 errors and redundant calls.
- Redundant version info was removed from the Help tab; management is now centralized in Settings.
- Information was added clarifying that OptiScaler 0.9+ includes FakeNVAPI and NukemFG in the bundle.
- The system now detects corrupt installations and suggests a cleanup before proceeding.
Fixes
- Linux Specifics
- A problem where disk paths in Linux appeared repeated or redundant was resolved.
- An issue where icons appeared broken across the app on certain distributions was fixed.
- Installation & Stability
- An error where performing an "Update" after an installation corrupted the folder was fixed.
