20 Games To Help Uncover Bottlenecks And Test Settings
Let’s reiterate a few background points for this two-piece article. We decided to analyze many popular PC games across a range of hardware and settings in an effort to identify key bottlenecks you might encounter on a fairly mainstream gaming PC. Do you need more than two processor cores for immersive gaming? Will a powerful graphics card work well, even if the CPU is weak? How much CPU and GPU performance do you really need?
In Part 1 of this article, we looked at Alien vs. Predator, Alpha Protocol, Anno 1404, Avatar, Battlefield: Bad Company 2, Bioshock 2, Call of Duty: Modern Warfare 2, Divinity 2: Ego Draconics, Dragon Age: Origins, and GTA IV EFLC. All were tested on an LGA 1156-based system. The Core i5-750 processor was configured with one, two, and four active cores and a 3 GHz clock speed. Additionally, we tried out four cores overclocked to 4 GHz. For graphics, we used a GeForce GTX 460 card, which provides sufficient performance for a solid gaming experience, but we also added a AMD Radeon HD 5870 here and there to look at potential benefits when pursuing high-end graphics.
So far, the results make clear that two cores are usually enough for gaming, but many games have specific requirements and performance characteristics. Let’s now look at ten more games and summarize the findings.

It's disappointing to see that devs still aren't taking advantage of multiple cores like they could.Reply
Would there be any performance difference between windows 7 32bit and 64bit?Reply
Assuming you use the same amount of RAM .
Great run down guys. I would of liked to see a three core benchmark thrown in there, but what can you expect from a dual core with HT.Reply
@KingArcher Unless the program was designed for x64, you had more than 4GB of unused RAM that the game could use and could use more than 4GB I highly doubt whether or not your on x86 or x64 would matter.
@nativeson8803 What difference would it make on games that are still GPU limited at two cores? Even then, there were games limited by the GPU at four cores. Taking advantage of a CPU with four cores or more is going to be hard when you need more GPU to get more frame rates.
@Slayvus almost true. The difference would be @2 GB of available memory. NT x86 kernel only allows an application to access 2GB of address space with the other 2GB reserved for kernel use. In NT x86 world each application can only access 2GB of memory, with the application getting rather unstable once it goes over 1.8 GB. This limitation also applies to the NT x64 kernel running a 32-bit problem through WOW64. Its something left over from the NT 4.0 / 5.0 world.Reply
Just keep in mind that these result are relevant in the context of using the GTX 460 768 MB, which is the real bottleneck here. Better GPUs and/or multi GPU setups would shift the bottleneck towards the CPU.Reply
In the end, it's all about finding the perfect balance in hardware. If you want my advice, pair the GTX 460 768 MB with a fast dual core, but get a good quad with higher end model GPUs.
This methodology should be used to new cpu/gpus/games reviews.Reply
I'd like to see them test the first Supreme Commander.Reply
It still taxes the most powerful systems
They should have used Phenom II X6 and test with 1/2/3/4/6 cores enabled. This made me want more of this because there aren't any 6-core benchmarks.Reply
Make a Part 3.

I understand that you're trying to go for the "norm", but if you're looking for bottlenecks, you need to remove said bottlenecks to see where it truly lays. Start with a quad core clocked at ~3.5ghz and swap out gfx from there. Push and push to see where it truly lays instead of going for a baseline. Although you can use that baseline to see what the "average" person might use. If the article is truly about the bottleneck, use something beefier than the 460.Reply
