minimum system requirements: hardware test vs final version

Post by Lex »

What's probability that if I was able to run hardware test with no problems at all then I will be able to play final build of the game?

My reason for this question are listed minimum system requirements - they say: Dual Core CPU and 512MB graphics memory. I have P4C Intel CPU (single core / hyper threading) and X1300XT with 256MB memory on board - yet, as I said, I was able to run your "demo" version without troubles so I hope the same should be for final version?

Sure thing. The final version is more optimised of the two, after all. It'd be very counterproductive for it to actually be LESS compatible than the demo...

To be fair, the final version will actually have things going on besides rendering that single scene, but yes, I agree - It's very likely you'll be able to run the game if the tech demo worked well for you.

My first thought: what a relief!
My second thought: I do hope that during this optimization process developers haven't sacrificed compatibility with fraction of % of systems-below-current-minimum-requirements to gain game runnable on tens of %s of modern systems. :D

In any case, it is too late for me as I've ordered the game. :P

On the other hand: Can I get any info how current minimum system requirements were calculated?

No no, the whole point of the test is to sort out all kinds of errors on as many systems as possible. They're not going to create more errors as they get closer to the release, so if the test worked out for you then the game itself will most likely also work. Low end machines were also included in this spectrum, so you shouldn't worry too much.

Besides, if you get errors in the final version you didn't get in the test demo, you can simply report them here, and hopefully have them fixed in a patch quickly.

"Low end machines were also included in this spectrum" - if they tested them then why selected minimum requirements are higher?
Is Dual Core CPU able to execute some instructions that Single Core HT CPU can't and developers were "trying" to use them?
Is 512MB graphics memory needed only for modern screen resolution (HD-like ones) while less memory is sufficient for the lower ones?

I'm sorry for all these question, I am just wondering. :)

No problemo, I'm a bit tired so I may easily overlook some things... :D

I believe that the minimum requirements are the specs you need to be able to run the game at a good, sustainable fps by the developers' standards. I have absolutely no clue how they calculated it or if they pulled the numbers out of their heads. It may be just estimates.

Another thing is that maybe some computers below the minimum weren't able to run the game, while some of them could, which is why they selected a requirement where the percentage of successful test were higher. That means, if you can run the game with lower than minimum specs, you should consider yourself lucky, because somewhere some guy can't run the game with a system equal in power to yours.

The single vs dual core in minimum requirements is kind of interesting.

For one it is becoming a trend, as in dual core cpu's are everywhere these days, which makes it increasingly easy just to state a common dual core processor as minimum requirement as opposed to stating an older, and less common, processor that may not be recognized due to its age (and cause confusion with the less computer savvy). Not to mention to run tests on old hardware means you need to get your hands on it.

Like Mameluk said, it is possible that they stated dual core as the minimum requirement because it gives them more breathing room basically. Not like bumping the min reqs up after release is really an option for them.

Well, at first, I was afraid that dual core CPUs could have some additional instructions. But I did a search and I've found that at current state it is even hard for programmers to program proper use of every core so this is mainly for OS / speed of execution (am I right here?)

In any case, as I said I've already preordered and I'm waiting for release so I can be one of first proofs of fail / success.

In its essence, threading is all about allocating calculations between two or more cores (either virtual or physical). If the program can't find more than one thread, it will calculate everything using that one. Thus, it's much slower than having two or more, for example, but it gets the job done nonetheless. So yes, you are correct, it only affects your speed. If there are methods in the code that are targeted specifically to be calculated by a certain thread (in your words, additional instructions), and that thread does not exist, it will NOT be ignored. It will simply be redirected to any other existing threads, which is the whole essence of dual cores being backwards compatible with single cores.
