@mitu I have pi 3 . I was almost certain I needed some type of rgb image file inorder to use crt tv with retropi from what I read online.
the problem was hdmi cable was connected aswell. I unplug restart and I have pictures on tv now . I am sorry that was such noob mistake! surprisingly Iam getting good image with all emulators . the smaller texts are not readable tho in emulationstation. I think I need to test some other themes.
thank you .

@mitu hi. I dont know if I should post new question or Just ask it here , since my question is related to this post .
the first crt tv that I tried composite cable with was 21 inch NEC . and I had no problem with . but today I tried it on 29 inch Sony trinitron . and I get slow video when Iam in a game . I can scroll thru games and emulators, with no problem but when I start a game , everthing get laggy and slow . I didnt do any config before and get perfect speed video on the NEC! do I need to change somthing u think ? is the slow video related to size of the crt screen? I have P3 b+ . you also mentioned you dont need any config on pi3. so not not sure where this isuue comes from. specially when I had no problem on the first CRT I tried !

@amook11 Please add some more info about your system - https://retropie.org.uk/forum/topic/3/read-this-first.

If you run tvservice -s from the command line, what's the output ?

Try with

sdtv_mode=16

and see if it improves the situation.

@mitu sure. thank you. its working now . I used the command you gave me. but I also removed the high res splash screen video which I have added few days ago! do you think the splash screen was causing the issue? becuse the slow laggy video was happening from the begging of the splashscreen! until the emulationstation menu , then again in games!!

I don't think so, the video splashscreen does not alter any video settings or impact the emulators' performance.
