What is a 3D rendering test?

A 3D rendering test measures how fast your GPU can render complex 3D scenes in real time. It benchmarks frames per second (FPS), frame time, draw calls, and triangle throughput using WebGL — the web standard for hardware-accelerated 3D graphics.

What is a good FPS in a GPU rendering test?

In a GPU rendering test: 60+ FPS is excellent (high-end discrete GPU), 30–59 FPS is good (mid-range GPU or integrated graphics under moderate load), 15–29 FPS is fair (integrated graphics or older GPU), below 15 FPS indicates the GPU is under heavy stress or the scene exceeds its capabilities.

What does the rendering score mean?

The rendering score is a normalized benchmark score that combines average FPS, frame time consistency, and triangle throughput into a single number. Higher scores indicate faster GPU rendering performance. The score accounts for scene complexity so results are comparable across different test configurations.

How to Read Rendering Test Results

What the metrics mean and how to interpret your score.

Score Range	FPS (Medium, 300 objects)	GPU Tier	Examples
8,000+	60+ FPS	High-end discrete GPU	RTX 4070+, RX 7700 XT+
5,000–7,999	45–59 FPS	Mid-range discrete GPU	RTX 3060, RX 6600, GTX 1080
2,500–4,999	30–44 FPS	Entry discrete / strong integrated	GTX 1650, Intel Arc A380, M2 Pro
1,000–2,499	15–29 FPS	Integrated graphics	Intel Iris Xe, AMD Vega 8, M1
Below 1,000	<15 FPS	Basic / legacy GPU	Older integrated, mobile GPUs

What each metric means

FPS (Frames Per Second) — How many complete frames your GPU renders per second. Higher is better. 60 FPS = smooth. Below 30 FPS = noticeably choppy. The live meter updates every second during the test.

Frame Time (ms) — Milliseconds to render one frame. 16.7ms = 60 FPS. 33.3ms = 30 FPS. Lower is better. Frame time variance (jitter) affects perceived smoothness more than average FPS.

Stability % — How consistent your frame rate is. 100% = perfectly smooth. Below 80% = noticeable stuttering. Calculated as: (1 - standard deviation / mean FPS) × 100.

Draw Calls — Number of times the CPU commands the GPU to draw something per frame. More draw calls = more CPU-GPU communication overhead. Shown per frame.

Triangles — Total triangles rendered per frame. A triangle is the basic 3D primitive. More triangles = more geometry detail. Modern GPUs handle hundreds of millions per second.

Score — Composite benchmark score combining avg FPS, stability, and triangle count normalized to scene complexity. Higher scores = better GPU rendering performance.

What affects 3D rendering performance and how WebGL works in browsers.

How this test works

This test uses WebGL — the web standard for hardware-accelerated 3D graphics — to render a scene of 3D objects using your GPU. Each object is transformed (rotated, scaled, translated) and lit by dynamic lights every frame. The more objects and the more complex the geometry, the harder your GPU works. The FPS meter measures how fast your GPU completes each frame of rendering.

What limits rendering performance

GPU rendering is limited by several factors: geometry complexity (triangles per frame), shader processing (vertex and fragment programs), texture sampling (VRAM bandwidth), and draw call overhead (CPU-GPU communication). This test is primarily GPU-bound — it stresses the shader units and rasterizer. For CPU-bound tests, look at physics simulations and game logic workloads.

3D Rendering Test – FAQ

What is a good score in the 3D rendering test?+

At Medium settings (300 objects, Basic Lighting): 8,000+ score = high-end discrete GPU (RTX 4070+), 5,000–7,999 = mid-range discrete (RTX 3060, RX 6600), 2,500–4,999 = entry-level discrete or strong integrated (M-series Mac, Intel Arc), 1,000–2,499 = integrated graphics (Intel Iris, AMD Vega), below 1,000 = basic or legacy GPU. Scores scale with scene complexity — use the same settings for comparisons.

Why is my FPS lower than expected?+

Common reasons for lower-than-expected FPS: browser GPU throttling (Chrome may throttle background tabs — keep the tab active), GPU power limits on laptops (plug in your charger), other tabs consuming GPU resources (close them), browser hardware acceleration disabled (check chrome://gpu or equivalent), outdated GPU drivers, or the test complexity exceeding your GPU's capabilities. Try reducing scene complexity or switching from Ultra to Medium settings.

How does this compare to desktop GPU benchmarks?+

WebGL benchmarks test the same GPU hardware as desktop benchmarks but via a browser API layer, which adds some overhead. Results are broadly proportional to desktop GPU performance but not directly comparable to 3DMark or V-Ray Benchmark scores. WebGL benchmarks are most useful for: comparing GPUs against each other relative to each other, detecting performance regressions after driver updates, and getting a quick GPU health check without installing software.

What is WebGL and why does this test use it?+

WebGL is the W3C standard API for hardware-accelerated 3D graphics in web browsers. It maps directly to OpenGL ES and talks to the GPU through the browser's graphics driver. WebGL lets browsers access GPU shader programs, vertex buffers, and texture units — the same hardware that games and 3D applications use. This means WebGL benchmarks accurately reflect real GPU capability, not just CPU-side JavaScript speed.
