Hey guys i've been using pcsx2 for a while now and recently I discovered perfect settings for my FFX, FF12 and Persona 4. I had these games running glitch free at 100% but then I got a new motherboard and I managed to overclock my cpu to 3ghz and its stable. Before my cpu was at 2.8ghz and the games were running at the highest possible with no slowdowns but now I started playing the games yesterday and FFX went down to 14% in the videos and 35% in game! wth hell happened there! Persona 4 runs at 50% the whole time. My computer specs are
CPU: 3.1ghz dual core
GPU: radeon 4870 512mb
RAM: 4gb
I have rogue galaxy and MGS3 too and they run at 50% so if i solve the FFX problem i believe it will solve those too. Please help anyone ill post any additional information if needed, thanks!

Bad overclock, maybe?? What exactly your cpu anyway?

Ah whoops forgot to say that I put it to stock speed and it didnt go any faster...all my PC games are working the same but pcsx2 isnt for some reason its a E4700 stock speed is 2.6ghz
Thanks

Does the FPS go up dramatically if you set d3d internal resolution to native?

Thats the setting I changed on mine when everything went slow, also set CPU to limit as well and all speedhacks off, advanced options at defaults.

My monitor res is 1440x900 so I picked a 4:3 res that would fit in that (1152x854) and set aspect at 4:3 and noticed no fps change between that and native.

Did you try getting the latest PCSX2 beta and latest GSdx revision to see if they make any difference?

well i did try the native thingy and all those options but it doesnt really change the fps...i fiddled around with settings and plugins and got it up to 60% but thats still a long way from the 100% i had before....yeah i tried the stable version of 0.9.6 and the newest beta...i used multiple plugins and the best i found was the 0.1.14 SSE3. i cant see what i would have done to make the fps go so low thanks so far guys!

To figure out the problem, what you really need to do is consider every change you made since it ran at 100%. If you backtrack the things you did 1 by 1, you may solve the problem, or atleast find out what the problem was. I assume it has something to do with the overclock to be honest.

Did you try one of the GSdx 1400+ revisions?

I found a document i saved which had all the settings for my games ( iwas smarter than i though ) so i copied that and had the same settings that got me the 100% but its still slow...it must be my hardware...could a mtherboard actually change the speed of the pc if the CPU does not change speed? i tried using the 1145 1451 plugins but they dont do anything different

I'm not really a hardware expert, but the bus speeds or clock speeds may have changed. There are a few hardware gurus on here, hopefully they'll pop in soon and give their 2cents.
