"Lazy" GPU in games?

post #1 of 5
Thread Starter 
Hey guys

I used to own a 590 which died last month and I went forward and got myself a sexy and cool (my gosh the temps are amazing compared to my 590) 780.

However in games now my gpu rarely wants to do more than 50% usage. This really annoys the hell out of me as I have 120hz monitor and I want my buttery smooth 120fps!

So far I've had these issues in fallout new vegas (get anywhere from 50 fps to 80 and usage from 30% - 50) and in borderlands 2 (fps from 100 to 30 and usage from 40 - 60). In CSGO I get about 200fps but this is again at lower gpu usages.

Specs of my build:

CPU: intel i7 2600k OC'd stable to 4.2GHz
RAM: 8GB Corsair Vengeance 1866MHz
MOBO: Asus Maximus IV Extreme
PSU: Corsair HX1000
GPU: Asus GTX 780 DCII
OS: Windows 8.1
Driver: 335.23

Or just check my sig.

Now I've tried setting the games to "maximum performance" in the power options of the nvidia control panel. I've tried running the games on low gfx settings, it's always the same. Before anyone says instability or insufficient psu I've run furrmark (one of the only place I've actually seen my gpu get to 99% usage) with no issues, I've run prime95 and memtest all came back ok.

The only way I can describe what it's doing is being lazy. In hectic situations the gpu usage just drops instead of increasing like it should to try and keep frame rate up. It's like it decided 50% usage was the max it can do and it won't do more. I thought maybe it's driver related as I've had one friend with a 7 series gpu who has the said he has the same issue.

Does anyone have any idea how to fix this or *** is wrong because I'm pretty disappointed that I can't even get 120fps in fallout, a game that came out 4 years ago. Any help would be massively appreciated.

I question the stability of your CPU OC.

The other possibilities are your HX1000 is dying (mine had been going out for about a year now. Just replaced it and magically all my little computer issues are gone), your card is reaching it's thermal/voltage throttle point and reducing its usage to compensate, or your game is choking on an I/O bottleneck.

Your i7 2600k is limiting your GTX 780. A much better cpu with huge overclock is required to achieve minimum 120fps in games such as Fallout 3 and Fallout: New Vegas. In general, older games are likely to be cpu limited, since older games often have simple graphics and often use less cpu cores. I played Fallout: New Vegas in 3D @1080p with my old GTX 580. In some towns, fps would drop to 30, but I was rarely ever gpu limited.

Edit: Here's something you could try. For some Bethesda games, there is a patch which enables use of newer cpu instructions. Older game engines normally do not use the newest cpu instructions. Search for a fallout 3 or fallout new vegas patch which improves cpu performance.

His CPU is fine does the same with my 980x 4.4ghz with lot of older games the problem is UE3 and other older engines and nvidia not re optimizing drivers with new GPU with older games


OP have you tried nvidia new 337.50 optimized driver?
http://www.geforce.com/drivers/results/74637

first use this to uninstall driver dont use nvidia method
http://www.guru3d.com/files_details/display_driver_uninstaller_download.html


My GPU usage went up for me with UE3 games went from around 50-60 to 60-80%

also you could always look into flashing a custom skyn3t vBios that will disable speedboost so you run at a fixed speed
this wont help GPU usage but should keep FPS more stable
http://www.overclock.net/t/1393791/official-nvidia-gtx-780-owners-club

OC GPU the 780 are great overclocking


Also your 4.2 OC is that with hyper-threading enabled? If so and you are limited to 4.2 because of heat.

Disable HT and you should be able to push clocks even more with possibly lower voltage.
Add another fan to you H70 if you haven't already for push/pull or invest in better cooler like H100 Ive seen people pushing 4.6 with that CPU and H100.
Core clock speeds are more important that HT with GPU scaling and games

Show me any benchmark of unmodded Fallout: New Vegas which shows minimum (or even average) frame rate at 120fps or higher with either AMD or Nvidia cards.
I have not seen such a benchmark and I don't believe it exists.

Here's another benchmark for you.
