From the store page:

(Sorry, I`m not allowed to post links)

SYSTEM REQUIREMENTS
MINIMUM:
OS: Windows 10 (+ specific versions of 7)

Which are the specific versions on Windows 7 ?

Not that I care about Win8, but is it not supported at all?


Cheers :)

Win 7 64 bit with SP1 and ALL patches (so it has DX11.1) and yes Win 8 (and 8.1) are supported
(there is no 32 bit support for ANY version of Windows, so you must be running 64 bit version)

Hi, I have only 6 GB ram installed. There is no other free ram slot on my mainboard and ram prices are very high in my contry mainly because of the currency. Can't I play pcars 2 on my pc. I was playing pcars 1 without any problem. I want to buy pcars 2 and it is very expensive too ,but first I want to know whether or not I can run and play.

You should be OK on low/med settings, and 6 GB should be fine.

Try it for an hour on Steam. If your system doesn't perform well and you have no plans to upgrade, just refund it.

and make sure to shut down everything you can before starting PC2 to free up as much memory as possible

Gosh, we have to wonder which graphical settings affect GPU and which affect CPU (aside from LiveTrack 3.0 weather where it's pretty much all CPU, hence the power required, not to mention how many threads pCARS 2 use, something I've already asked).

In my simple world view, anything that has different details levels is GPU. The heaviest GPU-related options would be:
- reflections
- env map
- shadows
- grass
- level of AA

Things that are related to CPU:
- damage
- weather
- LiveTrack
- AI

Regarding your last question: do you mean threads or do you mean cores?

Threads, not just actual cores, considering SMT (simultaneous multi-threading, or Intel Hyper-Threading) on Intel Core (for years!) and, just recently, AMD Ryzen.

(But are actual cores more preferred over threads itself?)

IIRC at least each tyre has its own thread, and distributed over the CPU cores equally. The rest I don't know, would need to have a look at Task Manager during game execution to see that I guess?

This still holds true in my testings Remco. When you monitor a hypre-threaded i7, you will see that 4 cores are heavily used while other task that can be split will take advantage of extra ones. Thus performance from 4-core processor to 8-core (real or hyperthreaded) is increased but (normally) not that whole lot.

Always excluding extreme scenarios (like 720p noAA with a 1080ti) but using normal configurations, jumping from an i5 4670k to an I7 4790k both running 4.3Ghz, will give you a small bump in performance but really small (I have the numbers, I'll probably post them next week after release).

This is due to that both processors are the same architecture and both can process the same amount of instructions per clock tick. So running at the same frequency they both perform exactly the same in single-core tasks (again, I have the numbers).

Then, adding the hyper-threading that the 4790k provides, assist the game/system in overall tasks so if you were able to run the 4670k at 90% capacity, going hyper-threading will give you a very small bump but better fidelity on the tyre. If you're running at 50% cpu on the i5, then the i7 won't help you a bit.

So, all in all, a FAST i5 4-core (or ryzen 5 maybe, haven't test those) will give you more or less the same experience than an i7 if you're pushing 60fps out of your GPU. If you're going for 120 or 144hz, then story changes quite a bit :)

Also, have in mind that (from my benchmarks) PCARS2 does a much better job CPU-wise than PCARS1. I found myself not using the "-skipcrowds" on my low-end systems since the engine was way better managing those configs and I also saw an increment of the amount of frames that the CPU was able to push before running into a bottleneck there. So, everyone... just bear with us for a week and you'll be pleasantly surprised.

Hope this helps further

Nice. This, and your upcoming tests will be useful. While at it, is there a list of other startup parameters too that may be useful?

Nope. Vanilla works just perfect. There are a couple of performance detection that will pick the right settings for you. The only thing is if you want to force VR or noVR in your case (assuming your signature is up to date)
