Hello,
lately my little brother's PC has encountered some weird issues, especially when playing in Battlefield 3, but the same seems to occur in NBA2K14.
But first here's the specs:
Motherboard - ASRock 960GM-GS3 FX
CPU - AMD Phenom II X4 965 Black Edition (Stock settings: 3.40GHz)
CPU Cooler - Zalman CNPS5X Performa
GPU - Asus Direct Cu II 650 Ti
RAM - Corsair Vengeance 4GB
PSU - Corsair CX430M
Monitor Resolution: 1280 x 1024 (4:3)
The problem:
Average framerate at Ultra Settings (No MSAA) at this resolution is around 60fps stable, very smooth, but quite often it drops horribly to 3-10 fps with resulting HUGE stutter for like 4-7 seconds. Final result: my brother is frustrated and the game is unplayable. This happens randomly, even looking at a wall, and even in 16 people servers, so it's not triggered by some effects, explosions or player cluttered situations.
A possible cause:
Watching MSI Afterburner I found out that these horrible and occasional FPS drops occur because in those moments the GPU usage goes to as little as 3% and then goes up again!! (what the hell?) .
CPU usage is always high during gaming, between 80 and 100% but this is totally expected.
Solutions I've already tried:
- Lowering the settings, even at lowest, doesn't solve the issue.
- Temps are OK (both CPU and GPU run at around 54 degrees maximum).
- I did a clean install of drivers with Display Driver Uninstaller, still the same.
- I tried SEVERAL different driver versions, even BETAs, still the same. Currently running the latest stable driver (335.23) .
- Tried a stable overclock, backed up by Prime95 5 hours test, at 3.8GHz, still the same.
- Disabled all power savings modes, both in BIOS, Windows control panel and NVidia Control Panel, still the same issue.
- Unparked correctly the cores, still the same.
- Checked inside the case, everything is plugged correctly and I removed all the dust from components.
- Resetted BIOS Defaults, still the same.
- Checked for file integrity in Origin for Battlefield 3, no avail.
Screen (the last part of the graph shows a constant 0% because I exited the game), this graph was took while approaching a wall with no enemies around so there wasn't any taxing effect going on:
So any ideas on why this GPU usage drop occurs and how to solve it?
Thank you in advance,
Patrick Kevin
