Tom's Hardware have taken down their benchmarks, apparently at the request of CDPR.
Honestly not surprised, incredibly unfair of them to run benchmarks on a preview build which was confirmed to be pre performance increase patch. It was nice to see where that specific build was at, but I'd hazard a guess we can expect at least 15% increase in performance. TOTAL speculation, but with matched drivers and performance patch and no DRM, that's what I'd expect. 5% increase from all 3 sources.
