The GPU definitely can bottleneck performance but unless you're running something horrendous like a 7 year old Quadro 2000 or thereabouts, the CPU computes what you see on screen. I've poked at a lot of Autodesk staff to get answers on how Inventor interfaces with hardware but few of them can or are able to give meaningful answers. The GTX 760, 770 and 780 where all more powerful than the Quadro K2200. So your K2200 was marketed for CAD because of the driver & vendor support, but in terms of power, I think it was roughly in the ballpark of the GeForce 750Ti which was never really a good gaming card either. I have a GTX 1070 in my desktop and it'll outperform any Quadro in Inventor, including the M6000, until the Pascal Quadros are released. The benefit of a Quadro comes via driver support and vendor support, which is required in business, but that doesn't make the cards perform any better with large assemblies than a gaming card. The M4000 has more VRAM soldered onto the board than the GTX970 but in terms of raw power they're as good as identical. Seriously they both have the exact same chip in them, same number of CUDA cores, same memory bandwidth, same throughput, everything. That has the exact same GPU chip in as the GeForce GTX970 which now retails for around £200. Good example, the Quadro M4000 is a very good but still mid-range professional card marketed at 3D CAD and retails for roughly £900. General rule of thumb for the scores is 1-5 is terrible, 5-7 is average, 7-10 is good, 10-12 is highest achievers with 12+ being the best of the best on todays hardware.Īgain apologies if you know about this but Quadro & Firepro doesn't mean more powerful than GeForce or Radeon. It runs a series of tests on Inventor on your PC and then gives out a numeric score which you can post here and compare it against other peoples PCs. I dunno if you have done already, but I'd recommend heading over to here and downloading the Inventor PC benchmarking tool that we've all been using to numerically score grade our systems. Hate to bring more bad news but your CPU is a bit of a budget Xeon, the E3-1220 v3 currently retails for £190 and given the consumer grade i7's retail for £300+, with the Extreme edition i7's in at £1000+, it possibly isn't as high end as you thought it was? Don't get me wrong it isn't terrible but again it isn't the best. FYI the Quadro K2200 is still a low end card, the K4200 would have been mid range with the K6000 being the high end, the K (Keplar) cards are now 2 generations old which doesn't mean they're bad but they're definitely not the best. Not sure who encourages people to buy powerful graphics cards for use with Inventor, there's a point in which a GPU becomes overkill as Inventor has always been CPU reliant in pretty much all areas including graphics performance. Happy to give more information to investigate. Surely something can be done to tip the workload to the graphics card. It seems clear to me the CPU performance is limiting graphics performance massively and its not like I have a budget CPU here. Watching my system performance as I move the graphics window I can see inventor hits 25% CPU usage (100% of one core) and doesn't go above this. I am wondering why we are encouraged to buy expensive Quadro graphics cards, when clearly they are underutilised. ![]() The GPU load rarely exceeds 10% and the memory load rarely exceeds 15%. Watching GPU-Z shows my graphics card is really doing very little. I am running GPU-z to monitor my graphics card performance and watching task manager to see what the system is doing.įor simple models everything is completely smooth, but with anything in the multiple thousand parts region or if using an AutoCAD DWG as an overlay the graphics window lags badly. I cant remember which, but it would be around 4 years old now. I have used a much less powerful system previously and had a much more responsive graphics window. This issue seems to involve all versions and is not operating system specific. ![]() I wonder if anyone is able to give some insight into what might be holding back the graphics performance of Inventor.
