    Hi HSG11 - welcome to RFO!

    That's a decent laptop and should perform well. You'll want HWA turned on.

    You can try one of the RFO benchmark tests just to verify that it's running Revit correctly and appears to be performing well on the benchmark.

    What do you mean by "super slow"... when is it super slow - always, i.e. just moving or modifying an element? or just when in 3D views?

    If it's super slow with everything, then the more likely issues are with the project model itself, i.e. how it was modeled.

    Hi iru69 and thank you for the reply. I just ran a standard RFO 2017 benchmark test and posted the results no another thread in this forum. My model is "super slow" in most views. I'have a pretty big floor plan (but only a building on 1 floor (3000m2)) and everything I do there is takes over all a lot of time. It's like it takes me 8hours to do something that would take me only 3 if the program would just run smooth. Dimensions are really slow, detail lines, filled region, section lines... pretty much everything. And the problem can't be that "the project is just to big" because the program is exactly the same as in my old computer (8gb ram vs 17gbram+ssd and a better graphic card).

    If you'll check out the attached picture could you tell me if this is normal ? because when I go tho the "get information on supported hardware" I can't find drivers for my graphic card.

    Best regards and thanx for answering Revit Hardware : CPU-videocard.png

    Ha! yeah, the new benchmarks were just released a couple days ago - bad timing. Honestly I haven't really checked out the benchmarks in some time myself, so I don't know if they're comparable to the v2 benchmarks, which there are a lot more results to compare against. I'm not looking to see if you set a new benchmark record or anything, but if your results are way, way off, that would point to a hardware/software problem.

    That everything is so incredibly slow on that laptop suggest modeling issues that you might want to take up in the general support forum. There are several threads on what to look for when model performance is really suffering (sorry, I don't have any links, but we should probably try to get one of those pinned since this comes up a lot).

    Finally, that dialog is totally normal and means absolutely nothing but what it says. Probably 75% of people using revit get that dialog (every workstation in our office has is). The Factory should really change the wording or just get rid of it since it causes tons more confusion than anything it's meant to help with.

    Is there really no "modelled" objects? Is the whole thing drawn using lines, filled regions etc?
    If so, that could be the problem. I think that I've read before that lots of lines etc can bog down a file.

    Not to mention totally missing all the value of using Revit. But hopefully that wasn't literal.

    Considering Y700 as I need affordable laptop for Revit (max half gig models), but then I saw your post and 2017 benchmark results. Can you disable Optimus? Solved: Disabling nVidia Optimus & Perform Clean Install - Autodesk Community

    Can someone compare i7 4th and i5 7th for running revit (not render, just structural model).

    I assume you're referring to Haswell vs Kaby Lake. I'm also aware of your other thread on a new computer, so I assume you're asking for budget reasons.

    If you're on a really tight budget, Haswell is still a fantastic CPU, especially on the desktop (laptops can better take advantage of the power savings of newer gen CPUs). A Haswell CPU will keep up very well with a Kaby Lake CPU. You can google lots of benchmarks, but the easy answer is from a value standpoint, Haswell is still an excellent choice.

    Hi guys,

    I wanted to ask some of you experience guys here about the current Revit 2017 CPU performance. My client has insisted on 6 core systems instead of 4 core ones for their workstations. I feel he has a lot to gain from the IPC and clock speeds of the 7700k rather than the 6800k. They now have a dedicated rendering workstation (dual xeon e5-2687w v4 & titan xp) so I want to ask him again regarding the fast 4 core 7700k over the x99 platform.

    Is there ANY reason to use the 6 core for day to day revit use? I cant seem to find any reason where this would be useful but I dont want to make an ignorant decision. I also wish Autodesk was more clear on this.

    Ryzen is on my radar but I feel the AMD chipsets need to prove themselves and I am not sure the IPC will be faster than Intel, guess we will find out tomorrow.

    Thanks as always!

    For day to day Revit use? I don't even know where there is any ambiguity, frankly. A slower six core will get beat by a faster 4 core, in ALL revit tasks aside from Rendering.
