Battlefield 4 [beta] crossfire cpu bug?

post #1 of 6
Thread Starter 
Anyone noticed this yet? My 7970s seem to be limited by my cpu (100%) in the beta so far. However when I disable crossfire CPU usage is fine. This is with latest 13.9 stable drivers and CAP 13.5. Anyone know a fix or should we just wait for AMD to release a CAP maybe?

BTW Crossfire didn't run AT ALL with 13.4 drivers so I upgraded to 13.9.

Something with BF4 Crossfire is definitely broken! My results so far:

-- i5 3570k @ 4.4 Ghz
-- 2 x PowerColor 7870 XT (Tahiti) in CrossfireX @ 1150/1550
-- Windows7 x64
-- Ultra Preset (4x MSAA and Vert Sync = ON) @ 1080p
-- BF4 Beta 64-player Conquest (After building falls)
-- FRAPS Benchmark for 300 seconds

Just to demonstrate that my rig is, in fact, properly configured for CrossfireX, here are my normal results for BF3 with all the same settings (Ultra Preset):
