The Warning Signs
This means your server is asking the game to load more texture data than the engine can handle.
The Culprit: 4K Import Cars
The standard GTA V vehicle texture is 512x512 or 1024x1024.
Most mods on GTA5-Mods.com are "High Quality" imports with 4096x4096 textures.
One 4K texture takes up 16x more video memory than a 1K texture.
When you have 5 custom cars in one area, and they all have 4K textures, you are instantly maxing out the video memory budget of many players.
The Fix: Resize Your YTDs
You cannot simply "increase the budget" indefinitely. You must reduce the asset size.
Method 1: The Glory Optimizer Way (Fast)
We built Glory Optimizer specifically to solve this error.
It will scan every single .ytd file, find the 4K/2K textures, and intelligently resize them to 1024.
Result: The warning disappears, and your FPS goes up.
Method 2: The Manual Way (Slow)
car.ytd in OpenIV.car.ytd.*Repeat this 50 times per car.* (Not recommended).
Conclusion
"High Quality" 4K textures are great for screenshots, but terrible for multiplayer servers. To run a stable server, you MUST optimize your assets.
