GTA 6 Trailer Analysis Suggests HDR May Be a Cheap SDR Upscale

HDR and tonemapping expert Filippo Tarpini analyzed the GTA 6 launch trailer and suggested Rockstar is using AgX tonemapping without an official HDR implementation. According to his findings and analysis by MusaRenoDX, highlights contain no extra detail, pointing to inverse tonemapping from SDR to HDR.

• Bright blue tones shift to purple in the trailer, a typical sign of per-channel tonemapping
• Analyst MusaRenoDX found no extra detail in highlights of the HDR footage
• AgX is suspected, which lacks an official HDR implementation
• HDR can only be evaluated after launch and fixed no earlier than the PC version
