WebGL Texture Constraint

Detection approach

WebGL MAX_TEXTURE_SIZE is only 4096 or lower. Consumer GPUs support 8192-16384. Low texture limits are a signature of virtualized GPUs or software rendering (SwiftShader, llvmpipe).

How this helps detect bots

This signal is assessed with other independent session, browser, and network evidence. A single anomaly is a lead, not a verdict; corroborating anomalies make automated traffic more likely.

Legitimate traffic to consider

Older hardware, tablets, or budget laptops running basic integrated chipsets.
