Hi guys,
just testing out SLI for the 770 Jetstream and I'm wondering how does guru always achieve this insane scaling of 90%+ in SLI listed in their reviews?
No matter what I'm trying I never achieve the performance boost I want.
1st test envoirment:
Win 7 64Bit SP1
ASUS ROG Maximus VII
Corsair AXi760
i5 4770K @ 3.8Ghz
4x4GB Gskill DDR3 Sniper @2133Mhz
2nd test envoirment:
Win 7 64Bit SP1
ASUS Z97-A
Corsair AXi760
2x4GB Gskill DDR3 Sniper @2133Mhz
i7 devil's canyon @ 4 Ghz
Looked up the usage of CPU,VRAM and GPU on Afterburner with OSD live, and neither CPU is ever really stressed out. VRAM isn't filled up and GPUs are mostly used to 50-70%.
I only have 2 games (the ones i need the performance for) and those are rFactor 2 and GTA 5. The only time I got high GPU usage for both cards is on GTA 5 in 2D with Downsampling on Ultra settings... but it's a nonsense setting with unplayable stutters but the only one where I get 90% performance boost over a single GPU
As soon as I try out 3D Vision and other stuff they always underperform.
Funny thing I noticed in GTA5 while playing in 3D Vision... Went by accident into windowed mode and GPU usage went from ~70% to 95% with an incredible FPS boost. what the heck is this?
I'd be very grateful for some advice here as I'm going insane about this matter and testing and researching non stop for 3 straight days. Oh, and CPUs are unparked, just in case.
thanks!
