Minecraft Bedrock: Best options.txt for Ray Tracing Tweaks

The primary goal for Minecraft Bedrock RTX optimization is Denoising and Upscaling Stabilization. Because ray tracing is extremely heavy, the game uses DLSS (NVIDIA) or TSR (Universal) to fill in missing pixels. This configuration focuses on disabling gfx_vsync to remove the “heavy” mouse feel and manually setting the raytracing_viewdistance to prevent the “light-popping” effect seen when chunks load.

File Path

The options.txt file for Bedrock Edition is buried within the Windows AppData packages. Ensure the game is completely closed before editing:

%LocalAppData%\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\minecraftpe\options.txt

Technical Configuration (The 2026 “Ray-Fix” Template)

Open the file in Notepad. Search for these specific lines and adjust their values. If you cannot find a line, you can manually add it to the bottom of the list.

# Minecraft Bedrock RTX Stability - GameEngineer.net
gfx_vsync:0
graphics_mode:3
raytracing_viewdistance:12
raytracing_denoiser:1
raytracing_upscaler:1
gfx_max_variable_framerate:0

Parameter Breakdown:

• gfx_vsync:0: Disabling this is the single best way to improve input latency in RTX mode. By setting it to 0, you allow your GPU to deliver frames as soon as they are rendered, which is essential for smooth camera movement in ray-traced worlds.
• graphics_mode:3: This forces the “Vibrant Visuals” / Ray Tracing mode at the engine level, ensuring that RTX-compatible resource packs (like Vanilla RTX or Kelly’s RTX) load their PBR (Physics Based Rendering) materials correctly on boot.
• raytracing_viewdistance:12: The in-game slider often limits this. Setting it to 12 or 16 in the text file provides a much better balance. Values higher than 20 can cause significant “light-leak” bugs where shadows fail to calculate properly in the distance.
• gfx_max_variable_framerate:0: Setting this to 0 unlocks the frame rate. This works perfectly with the gfx_vsync:0 tweak to give you a true high-refresh-rate RTX experience.

Strategy for 2026 Ray Tracing Stability

• BetterRTX Mod: In 2026, the BetterRTX community mod is considered essential. It replaces the default Minecraft RTX engine with a more optimized version that includes “caustics” and better “denoising.” It uses these same options.txt values but renders light much more efficiently.
• The “Glossy World” Fix: If your world looks glossy/metallic but has no shadows, it means the PBR textures loaded but the ray tracing engine failed. To fix this, toggle Fancy Graphics off and on again, or ensure graphics_mode:3 is set in your config before launching.
• Upscaling (DLSS) Tuning: If you have an NVIDIA card, always keep Upscaling ON in the video menu. In 2026, the DLSS implementation in Bedrock is very mature; turning it off will result in a 60% performance loss with almost no visible gain in clarity.
• VRAM Management: Ray tracing uses massive amounts of VRAM. If you experience “Pink Textures” or crashes, lower your Render Distance (not ray tracing distance) to 16 chunks. This frees up memory for the ray-tracing buffers.

Key Performance Parameters

Parameter	Recommended Value	Impact
VSync (gfx_vsync)	0	Removes input lag and “floaty” mouse feel.
RTX View Distance	8 – 12	Controls how far light and reflections calculate.
Graphics Mode	3	Hard-locks the engine into RTX/PBR mode.
DLSS / Upscaling	Enabled	Vital for maintaining 60+ FPS at 1440p/4K.

Conclusion and Expected Results

By disabling gfx_vsync and manually tuning the raytracing_viewdistance in your options.txt, you are removing the artificial bottlenecks of the Bedrock engine. You can expect a 20-30% reduction in input lag, more consistent lighting in large open areas, and a rock-solid frame-pacing that makes Minecraft’s ray tracing feel like a native feature rather than a heavy add-on.
