I had this also - Draftsight 2015 SP3, 64bit. I'm sure the previous post about sync to vblock is valid. For others, the problem is related to the speed of your pc graphics. Separate card or integrated - it still graphics speed. Here's why. I use Ubuntu 14.04 on several different PCs. E8400, 3 GHz, GMA4500 integrated graphics, Passmark 68 - lag is there. Not suitable for Draftsight, Wolfdale is before Sandy Bridge. Same PC with NVidia FX370 PCIe card, Passmark 91-100, lag is better. Still not suitable for Draftsight. G2120, Ivy Bridge 3 GHz, Intel HD graphics, Passmark +- 400, works fine. These have only 6 EUs, but it appears what each EU is able to do is key Mini PC, Celeron 2957U, 1.5GHz, Intel HD graphics, Passmark +- 400, fine. So you see - the CPU speed is not the factor. A 2 core 2 thread Haswell Celeron at 1.5 GHz, 4GB RAM, 12EUs is ok The speed of the graphics is the key. This shows Intel has come a long way in improving their graphics for 2D. I think a Passmark score of +- 400 results in no lag. So if you have the lag, you need faster graphics, not a faster CPU. Hope this helps - my 2 cents. |

I tried every solution and nothing worked. I managed to downgrade back to SP1. For the ones that want to do that. http://dl-ak.solidworks.com/nonsecure/draftsight/V1R6.1/draftSight.deb |

I just loaded Draftsight 2016 for Ubuntu and it has cured the mouse lag problem and on test is working well opening 8MB files. |
