Gran Turismo 4 framerate problem

[PlaysGames11]

jesalvein, I run plenty of softwares on my computer, such as Skype, Steam, mumble and others like that, but they are not eating resources at a point where PCSX2 would become that laggy ^^

markyrocks69, I understood what you said, but I think that on a FX 8320, if I run the game in monocore mode, it will be pretty *****. And by the way, I don't know where you got the fact that AMD frequencies are for decoration on the box, but it's wrong. Architecture is not optimized, this is true, but frequency is real.

well, If you're sure of what you're doing, then you probably know how to solve your problem...

[PlaysGames11]

And what should I do ?
Closing them did not solved my problem

[jesalvein]

could you please record a video of pcsx2 running besides your task manager shoing your CPU activity ? maybe it would bring us an insight on all this ...

[PlaysGames11]

OK I will do that a little bit later

Idk if you understood what I said or not but I wasn't suggesting you do anything except possibly overclock your cpu and see if that helps. And as far as amd chips go if the number isn't just for looks then why do every time you place an Intel chip of lower frequency and less cores up against an amd chip that on paper should trounce it that the intel is better? Regardless of what the reason is all the numbers ect really don't mean anything unless it translates to real world performance. And this is coming from someone who used to strictly buy amd. Why is that you ask bc I'd say hmm this one has 4 cores so does this but this one is 150$ cheaper. Then I found out what a benchmark was and boy did I have egg on my face.

Going on Intel CPUs was an idea I had before. But I don't have enough money to buy high-end components so I need to figure it out with AMD. But for now, I'll see what it does when I overclock it (i will try to get 5GHz).

In my experience 4.2 Ghz + is enough for most games on a Vishera chip in PCSX2. However, GT4 is very demanding, and I don't have it to test. At 4.4 Ghz my single threaded performance is ~1750 and that's pretty respectable, and at 4.8Ghz you would be around 2000 which is in Intel territory. Just for reference.

I don't know if you mentioned what type of CPU cooler you have in this thread, but seriously don't try to go higher than 4.2 on the stock AMD cooler. It's a complete POS, I was getting throttling at STOCK speed with it.

lol don't worry about my CPU cooler (Noctua NH-D14)

EDIT : I don't think CPU usage is the problem. The problem seems to be the fact that I have 8 cores and PCSX2 plugins doesn't support so much cores.
I say that because I noticed that it does not use all of my cores while playing (I disabled all power saving features that disable unused cores)

[Blyss Sarania]

Yes it only uses 2 cores, or 3 with MTVU. That is why single threaded performance is so important.
