The apparent jerkyness of a movement is irrelevant as long as the object being moved end up at the intended position. However, this jerkiness can be minimized if SU has less geometry to show. In other words, try to minimize the workload on the GPU (Graphic Processor) by using less demanding rendering mode like shadedinstead of shaded with textures, no shadows, no fancy edge styles, etc.
You can memorize rendering setups with scenes. For example, using Styles, create a minimalist rendering mode for work that you will use when modeling including moving and then create another mode that have all the bells and wistles. Create two scenes, each one using one of these styles. Disable, however, the camera position memorisation for these scenes to avoid loosing a crefully orbitted, panned and zoomed view.
Once that is done, you simply click on the minimalist scene tab to work. Your model will the respond fluidly. when ready to see it in its full glory, click on the other scene tab.
Note that with a relatively simple model, you shall not experience such jerkyness unless your graphic card is not very strong or you have disabled fast feedback or hardware acceleration or both in the Open GL preferences.
Thank you sire for the reply . i'm using the thinline mode with no colour..[purple and white faces mode] i have disabled only hardware acceleration because when i make a selection window, the monitor goes black with lots of coloured rectangle pieces scattered over it. i still have to find a graphic card driver update. i have a gigabyte brand motherboard, they still haven't released new updates π
