Visible trails further investigation

[Peter S]

I thought I would post this under a new topic as I think, after some further testing, that it is probably a systems issue rather than a bug but I canot see any consistent cause. Some people who replied mentioned monitors others video cards. My additional testing consisted of burning DVDs and NOT seeing the trails on my TV.

I have (I think) the same video card as Andrew NVIDIA 6600 GT - I get trails he does not. My monitor (Viewsonic 191s) has a 16ms reponse time which is perhaps slow by some standards but it is only 2 years old and is still a current model. Dom could see trails but his monitor appears to have 8ms response time which I thought was about as good as you can get??? Tom mentioned 10 ms and said newer LCDs are much faster. Is there a limiting speed above which PTE/monitor/video card cannot cope???

I would be most interested if anyone can shed any light on this

Peter,

I think it's problem with display's response time. And 16 ms. or 8 ms. don't say truth. For example, my LCD Sony SDM-M51 display has 50 ms. of response time, but in fact it has response time better than many 16 ms. displays I've seen.

Download this file and run both EXE files:

Please let me know about result.

Hi Igor,

Box_3D_engine: The box has fuzzy edges as it moves around the screen.

Box_CPU_engine looks worse as it has fuzzy edges but they are also jagged.

If we cannot rely on the quoted figures for response times and they are so far out how can we choose the best monitor to display this type of movement?

Kind Regards

Thanks.

These tests (with hardware acceleration and without) exactly show that the problem in response time of a display. Not in PicturesToExe.
