Running GTA V smoothly with two 1080 graphics cards connected via SLI is possible if you manage settings well.
You're experiencing low FPS in GTA V despite high GPU usage, which is unusual. It might be related to settings or background processes. Check if any background apps are consuming resources, and ensure your system isn't running too many heavy tasks at once. Adjusting display settings or temporarily disabling certain features could help identify the issue.
Consider testing with a single 1080 resolution, turn off SLI, and observe performance improvements. Check if scaling issues persist. Also, revert drivers to see if that helps. Your signature update is welcome!
GTA V dislikes GPU overclocks completely. I’m not sure why, but it’s the only game that doesn’t hit its full core clock no matter what I do. It still kept running above 60fps, which is good. I feel a shiver whenever I think about how badly GTA IV was optimized, so I won’t complain. As mentioned before, you can update drivers, reinstall them fresh, or roll them back. *note: Ensure Page File is enabled; GTA V shows memory leaks and sometimes needed more virtual memory.*
Your GPU overclock seems odd, especially with your 300MHz setting fully utilized in GTA V. It only decreases marginally—about 10 to 20MHz—over time due to heat limits, which isn’t a major concern.
