In GTA 5, using multiple GPUs doesn't improve performance compared to one dedicated GPU.
I just got my second GTX 970 SSC. The game played smoothly at a steady 60 fps when using one card at 1080p with a few settings adjusted, like shadows and msaa. But now comes the issue. With two 970s and the same settings, performance dropped significantly... What’s going on? I pushed graphics to their limits and got the same results. It shouldn’t have been worse than with one card. But frame drops kept happening—randomly and consistently. Checking GPU usage showed both cards running at 30%–70% instead of full 100%. With just one card, it was always at 100%. For The Witcher 3, everything ran perfectly since both GPUs were active. It looks like temperatures are lower in GTA 5 than in The Witcher 3, probably due to less usage. I reinstalled GTA 5 and updated drivers, but nothing worked. The only choice left is to reinstall Windows, which I really don’t want to do. Anyone here facing the same problem? Have you found a solution? How did you fix it?
The game isn’t available for SLI, or if it does, it might have issues with the feature.
The i5 4690 seems unlikely to cause any bottleneck with a 970 series card. Observing how these two cards handle other titles makes me believe GTA 5 isn't well optimized for SLI setups. It's puzzling why streamers keep posting smooth 60 FPS runs even when everything is pushed hard. Just to be clear, I reinstalled the drivers this time—this one didn’t include Nvidia Experience or 3D, which might have helped. The game ran a bit better, though frame drops remained. GPU utilization stayed consistent.
It's clear to me that Nvidia seems completely out of touch with the use of several GPUs. Perhaps I'm mistaken. Yet many express concerns about using multiple graphics cards, only to discover they have negative experiences. Their leadership has quickly shifted focus to corporate interests. The specifications for Kepler cards were particularly problematic—some users faced issues after a driver update failed to fully resolve them. Do they truly understand their target audience and why we care about investments ranging from $400 to $1,000? And why is Gsync structured the way it is? (this was just a thought) Meanwhile, AMD has a reputation for problems with Crossfire, which I’m still trying to understand. I haven’t encountered any issues on my end with multiple GPUs in the read team except for Battlefield 3, which experienced noticeable stuttering. Does AMD seem capable? Absolutely not! But Nvidia is clearly losing control and few people seem to notice. Someone will have to correct this...
You have a 780SLI setup and there are no issues in GTA. The performance is strong, consistently around 80-100 FPS.
