Games not utilizing all my resources, not boosting, lower than expected FPS. 240hz Gsync monitor + GTX 1070.

First I would look at is your CPU temps, but you said they are fine, but it could be a thermal throttle.

But what I suspect your problem is that your i5 750 is just not enough to push a 1070 at 1080p. At 1080p the bottleneck moves from the GPU to the CPU. Its like you are driving a race car in a school zone all day. You need a processor that can keep your 1070 fed to pump out the FPS or you need to move to 1440p which will move the bottleneck back to the GPU.

Hey all,

TL;DR: My games aren't using all my resources and getting less-than-expected/unstable FPS, benchmarking uses all resources and get expected/stable FPS. Also, quality settings don't reasonably affect FPS.

I have an older ASUS mobo with a 2.67 Ghz i5 750 (slightly auto-overclocked by BIOS) and I just got a new 1000W HX Corsair PSU and a EVGA 1070 SC, overclocked by about +100 Mhz (gets stable ~2100 Mhz in benchmarking).

I've been testing various games on various settings. I typically play MOBAs and a few FPS. When I play LOL, it loads up at 240 FPS at the start of the game and slowly starts crawling down as the game progresses. When the initial phase of the game starts its already down to about 160 FPS, during big fights it can drop to 120, and later on in the game it can get down to 90 FPS. HoTS is similar, but has lower FPS overall. I've tried lowering the resolution and the quality settings on both, somehow that lowers the FPS by ~10.

All that being said, in EVGA Precision XOC tool it shows my GPU sitting at 1595 Mhz GPU Core (the lower value before boosting) and 4000 Mhz Memory Clock. Open Hardware Monitor shows the same (it doesn't matter what settings I set in the game, it never boosts). League is a single-core game, but the main CPU Core doesn't get over 80% and usually sits around 60%, the RAM isn't remotely used up, the GPU isn't going into boost mode and is sitting at 50% utilization. Nothing is hitting anywhere near max values and temps are decent (60 C on the CPU, I may need to get that down).

I'm at a loss for what I can try to get my FPS to 240. I'd suspect CPU bottlenecking, but the hardware monitor is showing CPU under-utilized. Is there anything else I can tweak or test with? I just rebuilt this rig, so it's a brand new install from scratch, no bloatware and only OS, games, drivers, and antivirus installed. I have uninstalled/reinstalled drivers.

In Heaven Benchmarks it DOES utilize all the resources, hitting 100% GPU core and ~80% CPU.

On Extreme Full Screen I get these values:

And here's my rig, let me know if I need to upgrade anything. . . The Mobo, processor, and RAM are all old. If it matters I have 4 HDDs in a RAID10 for storage and 2 SSDs in a RAID0 for the OS (MOBO-RAID, not PCIE or OS/software RAID).

Suggestions?

your setup is WHOLLY inadequate for both a 1070 and high refresh rate gaming
