Computer majorly underperforming - What is the cause??

RinRanRyan · 21 Aug 2011 at 16:22

Hey there,

I have currently upgraded my CPU on my PC because of a bottleneck that was occurring whilst playing Bad Company 2. It was a dual-core and I upgraded to a quad-core AMD X4 640 which made the game go from completely unplayable to okayish on the lowest graphics settings but still with massive lag spikes when joining servers and when someone would plant a bomb etc. I have just looked up my specifications and my PC should be destroying this game yet it isn't and I have no idea why.

I just saw someone on Youtube with the same processor and a WORSE graphics card play the game on full graphics at 50fps which I find really peculiar. The graphics card I am using is an ATI radeon 5770 and I have 4GBs of RAM.

Does anyone know what could be causing this or have any suggestions as to what I could look into or change on my PC? I really feel it should be doing a lot better than this?

Thanks for the replies guys. I do only have a Corsair 400W PSU, do you think this is likely to be the cause?

How could I test to see if its a PSU bottleneck?

Okay thanks, now getting them...

What is the best way to get all my system specs? I used to have a program or web page that did it but now I can't find it....?

A quick go on that PSU calculator with just the RAM, CPU and GPU inputted already comes to 450W recommended without any hardrives etc added. Does this mean I should change the PSU??

Okay I am now trying that out now. Many thanks. Will report back in a second...

Many thanks to infernox, I rolled back to 10.x Catalyst centre and the problems resolved immediately. From 20 fps on lowest settings to 60fps on full settings so a pretty good result in all!

Many thanks
