if there's anything I might say it's the tracer girth at the moment. For daytime tracers I would say they are much thinner, but no dimmer at all. Same brightness, but thinner. At night, this "HDR BLOOM" effect occurs.. making them look wider

Just my 2 cents and IRL experience

Actually, this is from army footage probably, but exactly the same program I went through with the airforce. EXACTLY what it looks like with the naked eye (cept better quality-non-pixelated) and exactly how they look in CoD at the moment (yay!) But I think they're still too fat for daytime, when seeing them close to the aircraft.

Sometimes the tracers keep burning in the ground..



and here you go..



It's not a huge difference, but still.. It looks like a 20cm diameter tracer now, I believe it should look morel like 2-5cm max for < 8mm rounds
