Are these PC specs good enough?

    One of our league members is struggling to get rF2 running (on a tight budget). He's put together a new PC with these specs (I'm pasting these directly out of a long thread he started with):

    GIGABYTE GA-B250M-DS3H (rev. 1.0) LGA 1151 Intel B250 HDMI SATA 6Gb/s USB 3.1 Micro ATX Intel Motherboard

    Intel Pentium G4600 Kaby Lake Dual-Core 3.6 GHz LGA 1151 51W BX80677G4600 Desktop Processor Intel HD Graphics 630

    CORSAIR CX-M Series CX550M 550W 80 PLUS BRONZE Haswell Ready ATX12V & EPS12V Semi-Modular Power Supply

    WD Blue 1TB Desktop Hard Disk Drive - 7200 RPM SATA 6Gb/s 64MB Cache 3.5 Inch - WD10EZEX

    Crucial 4GB 288-Pin DDR4 SDRAM DDR4 2133 (PC4 17000) Desktop Memory Model CT4G4DFS8213 (adding another 4gb stick to that order today as I managed to sell an old car I've got sitting around, so bingo!)

    EVGA GTX FTW 660 2GB

    -----

    It seemed to me he was good to go, but I based my opinion (I suppose) on the PC specs I remember putting together for the initial release of rF2 some years back. He's very frustrated right now, and I think I'd better ask for some quick opinions from those of you who are better "system guys" than I am.

    Note: This is just a basic monitor-driving rig (single-screen, not triple or VR)

    Any ideas appreciated.

    550 W is to low. 750 W PSU is minimum.

    GTX 660 2GB is going to be bottleneck in rF2, I think minimum is GTX 760 4GB

    Im able to get on medium settings steady 60 fps with 660 ti and radeon 7870.
    Single screen full hd. This is with dx11 and no post effects.
    Havent tested the gt3 cars that could be more demanding for rF2 :)

    Pentium processor would be the bottleneck, a Pentium is just a rebranded Celeron with more cache basically.
    Not enough to run rF2, try an i series (i5, i7) but if budget is tight, from the i3-7100 up.
    Mainboard, memory, PSU and hard disk should be fine.

    @Christopher Snow It's all good enough, but the GPU could be better, a 770, 780 or 970, and of course 8gb ram.

    My friend @elnando8 is using a Pentium G4560 (so a little bit below the G4600) and the game run smooth as silk, DX11 and 40 cars online (GTX 970). Project CARS 2 run even better.

    I'm using a 530w PSU with hungry AMD hardware, never an issue in 2 years.

    500W is more than enough to hold a 4790K OC'd to 4 GHz and two GTX 970's.

    Go to clubedohardware.com/forum and search for "porque fabricantes de placa de video exageram no consumo recomendado" (why GPU manufacturers exaggerate power consumption) and translate the article, which was written by faller.

    I was gonna calculate the PEAK consumption of OP's computer, but @ceecee already did it.

    @Christopher Snow Your 500W PSU is more than enough for your rig. On it's PEAK consumption (maximum of the maximums), it draws 250W. Just don't go with outervision's 50W+ recommendation, ever, it doesn't make any sense. That's the only bad part of their calculator. If you have a 50W peak, they advise 50W more, and if you have 1500W peak, they also advise for 50W more. That's just ridiculous (same as pulling random numbers, like "750W is the minumum" :p )

    Instead, go for something like 20 or 30% more (which your PSU more than has) whenever your getting a new build/PSU. So if your peak consumption was, say, 450W at maximum peak (Load Wattage), you'd get a 90W+ with that calculation (better CPU, or overclock, or a new GPU, these 20-30% are a MARGIN for upgrades), so you'd get a 550W PSU just in case.

    Only if the maxes out every graphical option. I did this with my R9 270X 2GB and I was using around 1950 MB or VRAM. But a few details on medium and high, and no bottleneck happens.

    Recommended system power to single GTX 970 is 500 W according Nvidia but what does Nvidia know about GFX cards :p

    That's mean the whole approximate system, not the GPU itself, 750w are enough for a 1080 sli.

    Yes but do you get optimum performance from 1080 SLI with 750W ?

    They only recommend more power to be on the safe side, not because it's required.

    True. Two 1080 in SLI + i7 4790K OC'd + 4 DIMMS + usual stuff = peak consumption assuming all devices are at 100% all the time, which is unreal: 610 W Max https://outervision.com/b/qhFVvR

    A good 650W PSU would easily hold that config, though I would personally get a 850W once since the more you get near the PSU's max capacity the less efficient it becomes. But I think that's not so much of an issue with newer PSU's.

    You get it from 600.

    i7-4790k OC'ed to 4.7ghz
    GTX 1060 6GB ASUS Strix OC'ed
    16gb Ram at 2133Mhz OC'ed to ~2800Mhz.
    4 case fans, water cooler run at 100% for my CPU and GPU fans @ 100% all the time.

    Been running it for 2 years on my original 10 year old 650w PSU.

    The new Nvidia GFX cards use less power compared to years ago and so do the new MB's and processors.

    I believe that League mate to OT is going to use hes old EVGA GTX FTW 660 2GB and has used this card whit his old system running with PCI-e@2.0 x16. GIGABYTE GA-B250M-DS3H has PCI-e@3.0 x16 and obviously he is going to get performance boost in rFactor 2.

    Running at 1950 MB whit 2 GB ram is so close to the limit that vsync must be used to avoid that system ram is going to be used which most likely causes bottleneck.
    @stonec seem to have same opinion: https://forum.studio-397.com/index.php?threads/new-gt3-pack-now-available.58031/page-22#post-918831

    I'd recommend him to upgrade GFX to a GTX1060. Corsair 550W is fine, quality PSU.

    Just to info in 3DMark Time Spy my score 1080Ti Two-Way SLI and 750W PSU is 20156 and with 1500W PSU 20367, I wonder why ;)

    you can run that test multiple times and those scores will fluctuate.

    Video at 6:09. According to Linus' video, 1080 used 250/252W while 1080Ti used 329/330W. So 500/504W for 1080 SLI and 658/660W for 1080Ti SLI.

    You can look as many videos from Linus as you like. I have run 3DMark 100`s of times, and made measurements how much power my system needs to get 100% out from it. If you and other guys like to use low W PSU`s you are welcome to do that ;)

    You've ran 3DMark literally hundreds of times and picked one test score that equates to one frame per second in performance difference...

    Thanks for the opinions, help and ideas, folks. I've pointed my league-mate at this thread too, and we're discussing some of the things you've suggested. It seems his new GTX 660 was given to him by another fellow, and that is what made it possible (financially) for him to build the new system at all. It also seems that some of what I guessed were bottlenecks probably weren't after all and his problems lay with a broken install that didn't want to fix itself after verifying bad files (Steam)--a clearing of his download cache fixed that and he has now had a chance to drive around "old Spa" in a late sixties F1 car... :D ...which I told him was worth every penny of the $80 I spent myself for rF2 the first day it was released. As a long-time rF1 racer (his sub-league is currently racing an Eagle mod in rF1) I'm glad he's finally been able to move ahead...but they'll still keep racing rF1 too, I'm sure.

    He did also say that he was carefully monitoring his new system resources while diagnosing various issues and couldn't spot any bottlenecks at all. I'm going to have to ask him how he was doing that so I know too when my own next issues pop up.

    And last, he's going to try DX11, based on some hopeful comments above, though I'm sure DX9 alone has got him grinning. He must be liking it, as he graced his last post with a "dancing banana" emoji.... :D

    750W minimum? My god.... no comment....
    I run rF2 in a Core i3 2100 (I imagine that pentium is better) and a r7 360. 39 AI (S397 GT3 pack), all settings medium, 12 visible cars, PP low, blur/soft particles/reflections off, lv 1 AA (but when racing online to keep it more stable I run FXAA and shadows on low instead if I see we are going to have a big grid). That 660 is also better than my card I think (but people complain recent Nvidia drivers reduce their performance so if you believe conspiracy theory use older drivers lol). I get like minimum 40 fps (Silverstone, a newer track like NOLA min 50) in the start of the race with all the cars around me, it goes to 60 after the first lap
    Will you have issues with that system? Yes, the ones caused by rF2 bugs, but then even people with an i7 will have the same problems.
    Do I recommend running a dual core in this game? No. But if it is what you can get go for it, you'll be able to drive just fine. And then just hope devs will someday do their part fixing the bugs and making modding more consistent.
