To address the DLSS FPS issue in "Indiana Jones and the Great Circle" on PC, several workarounds have been suggested by users and developers. Here's how you might fix this:
Official Workaround: 
1.Switch DLSS Off and On:
2.Go into the game's graphics options.
3.Switch from DLSS to TAA (Temporal Anti-Aliasing).
4.Switch back to DLSS from TAA.
5.Exit the menu. Your FPS should return to normal shortly after. This method has been advised directly by the developers as a temporary fix for performance drops when DLSS is enabled.
Additional Community Suggestions:
•Toggle DLSS Settings: Some users have found that changing DLSS settings, such as toggling frame generation on and off, can restore performance. This might not be a permanent solution but can help in sessions where performance dips.
NVIDIA Control Panel Adjustments:
•For users facing frame rate issues or stuttering, adjusting settings in the NVIDIA Control Panel might help. Specifically, turning off "Low Latency Mode" or changing it from "Ultra" to "On" has been reported to mitigate performance problems.
Resolution and Upscaling Techniques:
•Experiment with enabling Dynamic Super Resolution (DSR) in Windows Display settings, then upscale to that resolution in-game, followed by enabling DLSS. Although not well understood, some users reported this method stabilizes frame rates.
Check for Updates:
•Ensure your graphics drivers are up-to-date, as NVIDIA might release game-specific optimizations. Also, check if there are new patches for the game that might address this issue.
General Performance Tweaks:
•If the problem persists, consider lowering other graphics settings like texture quality, shadow quality, or hair quality, especially if your GPU has limited VRAM, as the game is known to be demanding in terms of memory usage.
Configuration File Adjustments:
•Some users mentioned issues with texture pool size causing VRAM overflow, suggesting to lower the "is_poolSize" value in the game configuration file if one can locate it. However, specifics on how to do this weren't detailed in the sources.
Note:
•These solutions are temporary workarounds until an official patch addresses these issues comprehensively. Keep an eye on official channels for updates or patches from MachineGames or Bethesda.
•Remember, any changes to configuration files or using unofficial methods can potentially lead to game instability or loss of save data, so proceed with caution.
These methods are based on community feedback and official developer suggestions, but they might not work for everyone due to differences in hardware configurations or specific game bugs. If the problem persists, it might be worth waiting for an update or reaching out to support for more personalized advice.
