I'm Riza an Independent Advisor. Thank you for reaching out to the Microsoft Community. Let's work on resolving your issue together.
Here's a breakdown of potential culprits and troubleshooting steps based from the information you provided.
0x887A0005 (and 0x887A0006): These are very common DirectX errors in Call of Duty games. They generally indicate that the game is struggling to communicate properly with your GPU's DirectX components, often due to VRAM overload, driver issues, or corrupted game data/shaders.
0xC0000094: This error code is less commonly linked directly to DirectX in CoD contexts but can sometimes indicate a more general crash related to memory access or corrupted files.
Let's follow the steps below so we can start isolating the cause of the problem.
Here's a breakdown of potential causes and solutions, especially tailored for your situation and incorporating the latest information regarding these errors:
Rollback Drivers: Despite having the "latest" drivers, this is often the most effective fix for CoD DirectX errors. Many users have reported success by rolling back to specific NVIDIA driver versions. Look for drivers around 560.70, 561.09, or 566.36.
How to do it properly: Use a tool like Display Driver Uninstaller (DDU) in Windows Safe Mode to completely remove your current drivers before installing an older, known-stable version. This ensures no residual files interfere.
Do NOT update immediately: If a rollback works, resist the urge to update your drivers to the very latest as soon as a new one comes out. Wait for community feedback specifically regarding Black Ops 6.
In-Game Graphics Settings:
VRAM Usage: This is a major culprit. Even with an RTX 5070 Ti, the game might be miscalculating or over-utilizing VRAM.
Lower Texture Quality: This is the most impactful setting for VRAM. Try "Normal" or even "Low."
VRAM Target/Scale: In Black Ops 6 settings, there's usually a VRAM target slider. Try setting it lower (e.g., 60% or 55%).
Disable Overlays: In-game overlays from Discord, NVIDIA GeForce Experience, Steam, Xbox App, etc., can conflict with DirectX. Disable them all.
Disable Ray Tracing: While your GPU is powerful, ray tracing can be demanding and contribute to VRAM issues or instability. Try turning it off entirely.
Upscaling/Sharpening: If you're using DLSS or FidelityFX, try different settings or even disabling them temporarily to see if it affects stability.
Shader Quality: Try lowering this setting.
Reinstall Shaders: In the game's graphics settings, there's usually an option to "Restart Shaders Pre-loading" or similar. Do this and let it complete fully before playing.
If issue persists, let us know so we can check the Game File Integrity and other Windows settings and system level troubleshooting.
