I decide to measure my input lag with the HS camera of my work. I found why I am so slow. 100 ms delay (6 full frames) between the input in the wheel until it shows on screen. The video plays 20 times slower than real speed. Both laptop monitor and external TV showed similar figures.
Yes. I would say that both laptop monitor and TV have a big input lag. I might try with AC to see if the game has anything to do with it. However since I will be hopefully receiving my Christmas present this week I will not dedicate much time to it.
Invest in a gaming monitor,I can recommend ASUS 1ms slim bezel models,I run three and have no issues with them. They aren’t the most expensive or bling tastic but get the job done nicely,nice slim bezels so as time goes by you can add another two and have triple screen gamin Your new pc will run three no problems what so ever https://www.amazon.co.uk/gp/aw/d/B0...sus+vn247h&dpPl=1&dpID=41f-9G7qCGL&ref=plSrch
Very educational test, thanks ! A couple of questions.... what speed is the camera shooting at (approx) and do you have any ideas on limiting the lag (of course, without buying new hardware ! )
As the thread title says the recording has been done @1000fps to be played at 50 fps which is a slow motion of /20. I have no idea how to improve it. All I can do is measure it and try to figure out if it can be altered by some variable.
Some people recommend setting max pre rendered frame setting. Don't know what wheel you are using but in logitech software there is a test tab with virtual rendered wheel and there should be almost no lag. If you record that you can exclude your hardware
Pre rendered frames is for sli setups,the only thing you can do as far as I know to reduce input lag is to run as high fps as possible,but when it’s already that high,I doubt you’ll notice a difference,100ms is huge.
It's a G27. I already tried using the profiler and seemed to be the same (without measuring it: very noticeable lag. I have max prerendered frames set to the minimum which I cant remember if it is 0 or 1. I was running around 70fps in both tests.
Are you saying you have same lag in profiler? It is hardware/drivers issue then. I wonder what is normal minimum input lag and if games add their own on top of it.
He is still viewing the wheel display in the profiler on the same tv/monitor though,so of course he will still see the same lag. It’s the tv/monitor not the wheel that’s the problem.
Hi guys, I have a question I've been asking myself for a long time : Does the use of vsync help to create more lag input? By and large, 60 FPS without vsync is it equivalent in terms of lag input than 60 FPS with vsync? I use the vsync of RF2 : "vsync video". I do not use triple buffering (disabled in my video driver).
The best setup i found was: no vsync, fps limit in 123. Don't set the graphics too high, the objective is to stabilize in 123. With this configuration the stutter is gone, and the latency is way better.
With the new DX11 (non beta), that is impossible (really) to have stable > 100 FPS. Even for 60 stable FPS it is very difficult. And if I use AI, even few AI, it is almost impossible to have 60 FPS stable in all circonstances (rearview, 8:00 AM, mostly cloudy + rain etc.). DX11 performance is terrible for middle end computers.
@SPASKIS I use monitor 4 milliseconds and there is no visual difference, What cable to use? hdmi or displayport
