Half-Life 2 performance was measured using a custom demo that was created at AnandTech. The demo was recorded on level c17_12 and is close to a worst-case scenario in regards to performance. The demo is processor limited to a certain point as significant increases in performance from SLI do not appear until 4X AA at 1920x1440 and 8XS AA at 1280x960. SLI provided an average increase of 28%, which is commendable considering the circumstances.
