Good pc low fps

DumbMeat · Feb 9, 2016

Hello im getting lower fps in all games then i am supposed to get and i am experiencing alot of lagg spikes please help! (in gta i dont get full gpu usage and in alot of games only 98%)

gpu: gtx 970 msi 4gb
cpu: i7-3770
Memory: 8gb
Mobo: Predator G3620
psu: 550w
OS: Windows 8.1

Nvidia driver 361.75

your cpu and gpu are most likely struggling for power you need a much higher wattage psu

What wattage do you recommend?

TheLegendaryBanana · Feb 9, 2016

DumbMeat :

800 or better should be plenty

DumbMeat · Feb 9, 2016

TheLegendaryBanana :

Do you know any good but not to expensive one?

I did some research and i have read that 600-700w is more then enough

I doubt that the psu is any issue at all.
A GTX970 will draw a max of 225w.
If there were insufficient power, I would expect to see artifacts on the display.

Likely, the individual core speed of the i7-3770 @3.4 is occasionally limiting you.
Try an experiment as a backwards way to check.
Limit your cpu, either by reducing the OC, or, in windows power management, limit the maximum cpu% to something like 80%.
Go to control panel/power options/change plan settings/change advanced power settings/processor power management/maximum processor state/
This will simulate what a lack of cpu power will do.
Conversely what a 20% improvement in core speed might do.

You should also experiment with removing one core. You can do this in the windows msconfig boot advanced options option. set the number of processors to less than you have.
This will tell you how sensitive your games are to the benefits of many cores.

Another possibility is that the lags occur when checkpointing the game or logging.
Possibly when loading graphics info from the hard drive.

If you do not have a ssd, consider buying one.
Consider the source, but Samsung claims gaming improvements with a ssd.

yes but the higher the wattage the better off you'll be

I have changed it to 80% should i go test a game now? and what should i look out for?

geofelt · Feb 9, 2016

A psu will deliver only the wattage that is demanded of it, regardless of the max capability.
If a psu is operating at max capability, you will hear the cooling fan going full blast.

If the psu is a cheap unit, it may not deliver advertised wattage, or not deliver it to the +12v rails where a cpu and gpu need it.

Exactly what make/model is the psu?

that a dumb answer.

rgd1101 · Feb 9, 2016

did you add that 970 recently?

About a year ago.

geofelt :

I dont know i will have to open my pc later.

rgd1101 · Feb 9, 2016

how the temps on the gpu and cpu?

DumbMeat · Feb 9, 2016

rgd1101 :

gpu doesnt get higher then 80 in games like gtav
the cpu doesnt get higher then 60 most of the time, highest ive seen is 65

rgd1101 · Feb 9, 2016

DumbMeat :

screen resolution you are playing in? detail level?
still lagging if you lower the settings?

DumbMeat · Feb 9, 2016

rgd1101 :

I play on 1920x1080 i use the settings geforce experience gives me when i lower the settings i get a minor fps boost but i still get spikes

I would do what geofelt suggest, find out the psu make and model, although it probably a generic brand. time to get a better one.

Try dropping MXAA or different kinds of anti alias down and see if that helps, I know some games such as GTA where anti aliasing' over 2x at 1440P makes my 980 unhappy.

Alright do you recommend any good but budget psu? And as geofelt suggested i have put down something with the cpu to 80% should i restore it or try it with a game?

what you budget for the psu?
Yes. try what geofelt suggestion and try it with a game

Probably about 120 euros

i have been playing some Dying Light with the suggestion from geofelt, i still have some spikes here and there but the amount of spikes has reduced my gpu usage is 98% is this normal? Should i try putting it 20% down again?
