The Difference URP & HDRP

Hello everyone! Recently, there have been many newcomers (and also those who have been working with Unity for a while) wondering which Render Pipeline they should start a project with. Since Unity releasedScriptable Render Pipeline (SRP), we have said goodbye to Built-in the old Render Pipeline and moved on to two more powerful choices:URP (Universal Render Pipeline)andHDRP (High Definition Render Pipeline).

URP (was previously Lightweight Render Pipeline - LWRP)was born with the overarching criterion:"Write once, run anywhere, with the highest performance".

🌟 Key features:

  • **Absolute optimization:**very lightweight, intelligently handles draw calls, aiming for high performance (especially important for hardware-limited platforms).
  • **Perfect compatibility:**runs super smoothly on Mobile (iOS/Android), WebGL, Nintendo Switch, and standalone devices VR such as Meta Quest (Extremely solid graphics:).
  • **Although called "lightweight," with recent updates,**it has done many incredible things URP including support for Deferred Rendering, (beautiful visuals, Decals... Post-processing 🎯 Best suited for:).

Mobile games

  • Hypercasual, (, Hardcore mobile should all use it Mid-coreGames).
  • 2Dwith a separate 2D rendering system and an excellent 2D lighting tool (URP Indie games or PC games aimed at the mass market).
  • for audiences with mid- (to low-end computers-Games with a).
  • Stylized,Standalone Cel-Shading, Low-Poly.
  • VR Oculus Quest (High Definition Render Pipeline: "Beauty beyond limits").

2. HDRP - was born with the mission of elevating Unity's graphics to the same level as

HDRPand even surpassing (other popular engines on the market. Its criterion is:) to push graphics to the highest level, without worrying about weak hardware HDRP 🌟 Key features:Photorealistic.

Realistic graphics

  • **applies Physical Based Rendering (PBR):**complexly. Metal surfaces, human skin, glass, cars... look real. (Extremely powerful lighting system:) supports Physically Based Lighting
  • measured in Lux, Lumen, Ray Tracing, Volumetric Lighting (volumetric lighting/God rays), and global illumination (Global Illumination)in real time, which is extremely powerful. (Material) Material
  • high-end: (supports Subsurface Scattering) to make skin and flesh look realistic, Clear Coat, Anisotropy. (Extremely hardware-intensive:)only works on
  • that support Compute Shaders. Don't try to builddown to Mobile, it will crash badly GPU 🎯 Best suited for: HDRP AAA or AA games on PC / Consoles! 😂

3. Detailed Comparison URP vs HDRP

Below is a comparison by each criterion so that everyone can easily picture it:

  • Main objective:
    • **🟢 URP:**High performance, absolutely optimized for multi-platform support.
    • **🔴 HDRP:**Hyper-realistic graphics, delivering the visual pinnacle.
  • Supported platforms:
    • **🟢 URP:**Mobile, WebGL, Nintendo Switch, VR (Quest), low-end PCs.
    • **🔴 HDRP:**PC (mid-range configuration and above), Consoles (PS5, Xbox Series), PC-VR.
  • Lighting:
    • **🟢 URP:**Basic support for Forward / Deferred Rendering.
    • **🔴 HDRP:**Advanced Deferred Rendering, physically accurate interaction down to every Lux/Lumen.
  • Premium features:
    • **🟢 URP:**Moderate support (No Raytracing).
    • **🔴 HDRP:**Full Raytracing, Volumetric Clouds/Fog, extremely powerful Decals system.
  • Materials / Shader:
    • **🟢 URP:**Only standard shaders (Lit, Baked Lit, Unlit, 2D Lit).
    • **🔴 HDRP:**Diverse physical shaders (Subsurface Scattering for skin, Hair for hair, Eye, Clear Coat...).
  • Learning/Setup time:
    • **🟢 URP:**Extremely quick to learn, very approachable and easy to set up.
    • **🔴 HDRP:**Complex system, steep learning curve, requires a lot of in-depth knowledge.
  • Project size:
    • **🟢 URP:**Compact, fast build speed.
    • **🔴 HDRP:**Very heavy, takes a lot of build time.

4. Practical Advice from Real Experience 💡

Having once been "stuck" in a few projects and spent months porting from HDRP to URP (and vice versa), I’ve distilled a few golden rules for you:

IMPORTANT

Golden Rule:If you don’t know which Render Pipeline you SHOULD choose when you’re just starting out, always chooseURP. More than 90% of today’s games are completely fine and run smoothly on URP.

  • **Mobile = URP:**No need to think twice. If you want the game on mobile, stay far away from HDRP.
  • **Switching pipelines is a wasteful risk of time:*Although Unity has the"Render Pipeline Converter"*tool, your custom shaders will break, lightmaps need to be recalculated, and the config is a headache too. Lock in the Pipeline from "Day 1" of the project system design process.
  • **Don’t be too blindly focused on the platform:**You must clearly define the "Art Style" you are aiming for:
    • Stylized graphics (cartoon, Low-PolyAnime...) ➡️ Choose URP (Optimized combined with Custom Shader/HLSL and it looks very beautiful).
    • Grand realistic-style graphics, extremely lifelike reflections, houses full of artistic cinematic fog ➡️ ChooseI hope the article above can clarify these comparisons and help you save a lot of time as well as costs when you have to change the Render Pipeline halfway through HDRP.
