Far CryFar Cry is run using SFR over three test scenarios and three resolutions per scenario, examining the performance to be gained from SLI with and without HDR rendering enabled.
At the median setting, we see the 6600 GT SLI combination creep up on a single 6800 GT. The upper setting takes its toll on NV43 in SLI however, performance falling off slightly and the combination not able to accelerate rendering enough to keep pace.
As we've seen before with the 6800 boards, HDR rendering as implemented by Far Cry isn't able to be accelerated by SLI, leaving the SLI setups floundering.
More of the same with HDR mode 7, just with even less performance, to highlight that software plays its part in SLI performance and that adding another card doesn't always guarantee extra performance.
