SLI setting makes frame rates drop??

[bluesageq]

hi currently i enabled the SLI settings on my 2 GTX 980 TI gpus and i was expecting to get better frame rates but instead they would just drop with every game that i had started the current specs of my computer are:
Dual EVGA GTX 980 Ti Hybrid
CPU: Intel Core i7-4790K
(2x)RAM: CORSAIR Vengeance Pro 16GB
Motherboard: GIGABYTE G1 Gaming GA-Z97X
Case: AZZA Genesis 9000 CSAZ-9000B
Power Supply: Corsair Professional Series AX 1200 Watt
Liquid Cooling: Corsair Hydro Series H100i GTX
(2x) HDD: WD Black 6TB
SSD: Solid State Drive, 256GB
(3x) Monitor: BenQ XL2730Z 144Hz 1ms 27 inch

my computer should be able to support sli and i dont exactly know whats wrong... any help would be great! thanks in advance!

Games only use SLI correctly if the game developer took the time and effort to write the code to support SLI (and/or Crossfire). That code us very complex, and can be very buggy. So many game devs just never spend the time working on that.

@MarkW

Most of multi gpu effort was done by gpu maker. Hence SLI or CF profiles was released by gpu maker. Game maker usually just help to make their games works better in multi gpu setup. But if their game end up using stuff that will not working well with SLI/CF most often nvidia/ amd will not going to work to support such games in SLI/CF. so most often when it comes to sli or cf gane developer are not really involved with it. That's why we can have one game have day 1 sli support fron nvidia while for amd the support can come three or for four months later for the very same game.

Have you tried reinstall your drivers? What games did you play?

Well, "oh well" is really all I can say here. Nothing you can do about it if it doesn't work.
