Fake Quad Core.....

[goyalrahil2]

Hi,
I have dual-core CPU and there are some game like Fifa 15 which require quad core otherwise it will lag but I know that my CPU will able to play that game so is there any way in which I can fake core?
Thank you very much....

Usually, even though they say a game says it requires certain specs, the game will still start fine without them.

Do you have an i3 with hyperthreading?

 

[PhatLloyd]

I'm a perfect example. Most games require quad core cpus, do I care? Not a damn. I will run everything with my dual core that's not even a n i3. So it doesn't mtter even if you only have a dual core.

The game does start well. However, it lags a lot when playing. Its basically unplayable... So

That's probably just your CPU or GPU. Almost certainly not deliberately crippled - why would you?

 

[slyu9213]

Faking a Dual core as a Quad core (not possible) wouldn't help in your situation. EA is recommending a Quad core because the PC version runs the ignite engine now.

You can already run the game meaning they did not code the game to run bad purposely. In this case you just don't have a strong enough CPU or GPU.

As above, the code doesn't work like this:

"Oh I am running on a dual Core CPU, I will intentionally lag"

There is no faking hardware.

The issue could be driver/software based, but it is far more likely your graphics card, which is by FAR the most important aspect when it comes to gaming.

How much RAM have you got as well? And what settings are you running the game at>

Post ALL your specs, if you're trying to game with the igpu, then thats your problem.

FIFA 15 - http://www.game-debate.com/games/index.php?g_id=9278&game=FIFA%2015

Put your PC details into that screen and it will show you how well you can play the game. Note the increasing requirements for CPU, GPU and RAM for higher game settings.

 

[James Orme]

goyalrahil2! You started this come back and tell us your specs!!!!!!!!!!

If you don't know how to get these ask us and we will tell you how!

 

[James Orme]

Post ALL your specs, if you're trying to game with the igpu, then thats your problem.

What he said. If you are using an integrated Graphics card then you definitely will get lag. You need a very decent integrated chip to play even at low settings. Get a dedicated card for any chance of playing the game on your rig.

GPU : AMD R9 280 Dual x OC

Sorry for the delay guys. However, I don't need the answer any more because i now got quad core i5 but please do post your opinion so it can help others.
Thank you very much

Well no wonder the game ran so slow. It was a pure Dual-Core without HT to allow 4 threads. At least we dont need to help you as you have your i5 which won't be an issue with basically any game

Well, in Dragon Age: Inquisition, they hard locked one of the heavy workload threads to Core 2, which basically forces a quad core CPU. Ubisoft did a similar thing in Far Cry 4. In both cases, there's unofficial patches to move that thread allowing Duos to run the games.

So yeah, Devs are starting to force quad cores, even when they aren't really necessary. Which is going to cause major problems down the line is Duos become more powerful (DX12, new CPU arch) and we have a generation of titles that won't run due to artificial hardware requirements.

 

[Someone Somewhere]

Ah, OK. That's... interesting.

Out of curiosity, are the cores numbered from zero or one, and is it core two or thread two?

The OS counts them starting from Core 0, so Core 2 is the third core.

 

[Someone Somewhere]

Thought so. Wouldn't make sense otherwise.

Does HT fix the issue?

 

[gamerk316]

Yes, since, as far as the OS is concerned, a HTT core is fully usable. Granted, performance may tank due to where threads get assigned, but it will WORK.

At least on Windows, every "odd" numbered core is a HTT core when HTT is enabled. So cores 0, 2, 4, 6 are "physical" cores, and cores 1, 3, 5, 7 are "logical" cores. Which makes the FC4 case so funny, since Ubisoft forces a heavy workload thread on Core 3, which will TANK performance on any HTT enabled CPU if Core 2 ever gets used at the same time.

Do you have a specific link to where this is disclosed? I might want to bring this to the attention of some folks I know who know folks over at Ubisoft.

Do you really think the software engineers at Ubisoft need you to make them aware of anything? Lol!

Core 2, not 3, but same point still holds: Forcing a thread to Core 2 forces at least three CPU cores for the game to run, even if doing so isn't strictly necessary. I'll see if I can dig up the original article on the subject.

A second problem is why a 64-bit .exe file is invoking 32-bit DLLs. Points to some REALLY shoddy coding practices.

I'm pretty sure that's not quite how HT works. Neither of the two threads based off one physical core is different to the other.

A quad-core with HT has four physical cores and eight logical cores, because each physical core shows up as two logical cores.
