BUG:BG3 launch error

[FREDbarry001]

Steam deck OLED

Proton-GE10 (tried different proton layers)
Decky framegen 0.15.0

When booting up the game i get the next error:

Assertion failed!
Program:
Z:\home\deck.local\share\Steam\steamapps\common\Baldurs Gate3\bin\bg3_dx11.exe
File:
D:\a\OptiScaler\OptiScaler\OptiScaler\include\imgui\imgui_draw.cpp
Line: 3129
Expression: "(0) && "Could not load font file!"

Press oke to exit the program, or cancel to start the wine debugger.

When pressing Ok: game closes
When pressing cancel: Fatal error

When unpatching the game the game works again
But it works fine in Decky framegen version 0.13.0.

I had similar issue here. I can't understand why installing 0.15 Framegen then use LSFG-VK cmd "LSFG + DuckyFG" cmd would get this error.

If I use only the LSFG-VK cmd, it could work but DLSS option was missing, and FSR option couldn't get the smooth experience that I was expecting.

However, if I had used the DLSS Enabler mod, I can select the DLSS4 and are able to run the game very smooth. i don't understand why i cant use the FG as easy as in the plugin and where my mistake goes.

Yes, this error occurs with many games from version 0.13 onwards!

Seems like it can be fixed by doing the following:

Have the following installed and setup in Deckyloader:

1. LSFG-VK
2. Framegen

Then do the following:

1. Run the game with Framegen uninstall cmd.
2. Remove Framegen setup in Deckyloader.
3. Install Framegen setup.
4. Copy LSFG + DuckyFG cmd.
5. Run the game. You'll see the "Optiscaler" text in lower left screen, and DLSS/DLSS4 option appear in game settings. Use DLSS option.
6. The choose this option:

• Upscaler: FSR3/4
• FFX: FSR 4.0.x
• FG Input: No framegen
• FG Output: No framegen

7. Open Decky LSFG-FK in Deckyloader and set:

• FPS Multiplier: 2x or etc
• Flow Scale: 100%
• Base FPS Cap: 60FPS
• Present Mode: FIFO - Vsync (Enabled)
• Performance Mode: Enabled
• HDR Mode: Enabled

After this point, the LSFG and Framegen should've do its magic. I noticed theres no input lag on Frostpunk 2 if I use No framegen on FG Input and Output in Insert menu and it's a smooth experience.

Frostpunk 2 is a DX12 games, and i think some games that's not DX12 mighy need to run with just the decky LSFG-VK only.

Okay, I will test it again following your instructions later. I will provide feedback on the test results.

No matter what I do, I always get this same error.

Do anyone found solution for the font error?

[Mromerolillo]

With the last version of the plugin I dont get the font error but the games crashes at launch anyway :(
