I recently bought a GTX 1080 AG 8GB, It's boost clock is 2017 MHz. However, when I try to run games the GPU sits at 30-45% usage, despite the frame rate significantly varying form 20-80 FPS in the two games I've tested it with: Rust & Planet Coaster.
I've done A LOT of reading on the subject, and noticed it seems to be a common issue with no clear resolution. So I'll try and consolidate all the suspected issues into this post, with the hope that this can be resolved in a manner that others can follow.
Basically the issue is the GPU isn't cranking up to provide a steady frame rate, it's simply sitting at 30% the majority of the time. I've never seen it go above 60% usage in games at all. Benchmarks however do push the card, it seems to be only games that the GPU isn't pushing itself for. My understanding is the GPU should go to 70-100% to provide as many frames as it can, unless V-Sync is enabled. So why is my 1080 not pushing itself to provide more FPS? I understand that the card is intended for 4K, I purchased it to future proof, but it doesn't make sense that it's not pushing itself to run at 1080p... I've checked the following commonly suggested troubleshooting tasks:
1) Suspected CPU Bottleneck
This is very unlikely. I have an I7 3770K overclocked to 3.9 GHz, and I actively monitored the individual CPU Cores utilisation ~ they're never used more than 50-60% per core. Temperatures are also never above 60°
2) Enabling Performance Mode & DSR (4K) in Nvidia Control Panel
I've enabled Prefer Maximum Performance in the control panel, as well as Dynamic Screen Resolution (DSR) to try and run the games in 4K on my 1080p screen, to try and get the card to run at a higher FPS/use more power. This made no difference.
3) Remove Drivers & Re-Install
I've used DDU to remove all display drivers (including integrated) from my system in safe mode, and then re-installed the latest driver 382.53 - WHQL.
4) Check for Windows Updates
No windows updates available or pending.
5) Setting FPS Target in ASUS GPU Tweak II
I tried setting the FPS target to 250 FPS, this made no difference.
