ExplosiveViper Posted January 4, 2016 Share Posted January 4, 2016 Normally I get 60FPS in gta on mostly Very High settings. However every minute or so my FPS drops to 20-23FPS for about 10 seconds. During this time my CPU speed drops to 1.3GHz. Is this causing the FPS drop? I have tried playing with everything set to normal, but i still get the same pattern. 60FPS+ for a minute or so then down to 20FPS. CPU utilization is usually at 70-85% during gameplay. I have tried with and without mods. With and without V-sync, etc, etc. Can anyone help? Thank you for your time.

RedDagger Posted January 4, 2016 Share Posted January 4, 2016 It might be your CPU overheating, use a program like Speccy to see the temperatures of our CPU as you play. Flachbau 1 Link to comment Share on other sites More sharing options...

Flachbau Posted January 4, 2016 Share Posted January 4, 2016 Adding onto what Dagger said, it's most likely thermal throttling (the official terminology for that ). Speccy isn't always very accurate.. I would recommend CPUID's HWMonitor. Link to comment Share on other sites More sharing options...

HWMonitor gave a reading of 48 Celsius (112F) while idling and 56-57 Celsius during gameplay. During lag spikes, there was no constant changes in temperature. Ei: sometimes it would increases by a degree sometimes it wouldn't. Link to comment Share on other sites More sharing options...

I also tried lowering resolution with no success Link to comment Share on other sites More sharing options...
Flachbau Posted January 6, 2016 Share Posted January 6, 2016 Those temps aren't very out of the ordinary. They sound normal to me. Maybe it could be due to your power supply? Link to comment Share on other sites More sharing options...
ExplosiveViper Posted January 6, 2016 Author Share Posted January 6, 2016 (edited) Those temps aren't very out of the ordinary. They sound normal to me. Maybe it could be due to your power supply? My power supply is only 450w. Now that I think of it that could be the problem. Edit: Do you know of any software that could help show if this is the problem?

stretchx9 Posted January 6, 2016 Share Posted January 6, 2016 (edited) Yeah, it's likely you could use a better PSW and you can check it and your motherboard VRM's for voltage droops with HWMonitor or AIDA-64. A single 12v rail 450 watt psu is just asking for trouble with a power hog like an FX8350. I use a watercooled 8350 and a single gtx970 and some times my Kill-A-Watt registers in-game power consumption above 480 watts, when I use 2 970's in sli it can go well over 600 watts! It could be a no-brainer like your'e using a cheap extension cord or power strip. It also could be sound driver conflicts. Disable all incidences of Nvidia HDAudio in your device manager.

I removed a power board and ran my computer directly off the outlet. However this didn't help :-( If not to sure how to read the Voltage info on HWMonitor. Will this help identify whether the PSU is the problem? http://imgur.com/YBSpd7W(Screenshot is after 30min of gameplay). I didn't notice any voltage drops but that might just be due to my lack of understanding of how it works. Link to comment Share on other sites More sharing options...
