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
Collect this signal alongside session context, request metadata, and other independent indicators. 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.
