Question / Help Problem with OBS... Decent PC with smooth gameplay but laggy exported video

[GreekPotato]

So my pc spec is:

8GB Ram (Crucial Ballistic 1600DIMM)
CPU i5 4460 3.20GHz
2048MB Gigabyte Geforce GTX 750 Ti OC
ASROCK Pro4 Intel B85
650 Watt PSU Antec VP650M
1TB Seagate HDD 7.200RPM(where I save the video)
SSD 250GB(the windows 7 and where the obs main install is)

It's been 3 days since I bought my pc and the temperature is pretty cool with my two extra fans that I added to my case (4 in total/6 if you count CPU's and GPU's)

So I try to record Call of duty 4... without recording I get 350 fps(with 20% cpu usage). But when I record(max resolution+quality) I get ~150 fps(with 60-73max cpu usage), which I don't complain since I have a 60Hz monitor... Though when I open the video I recorded... it is very very laggy like 10-15 fps... I tried most of the recommended settings in the forum, from two youtube videos and a reddit post.. but still the same thing. Even if I try to record 360p... the video is laggy.

I find it weird 'cause I watched a guy recording gta v and getting 40-50 fps with medium/high settings using ShadowPlay...

Obs log missing.

Here is the log.

Your nvidia graphics card is slowing everything down. It could be driver related, it could be because of nvidia's new "share" thing, but it's causing a MASSIVE slowdown.

And there's no point in going crf=1, crf=15 is plenty.

Your system is not up to the task of recording at 1080p60 while you run a game without vsync at the same time. Try enabling vsync or some other type of frame rate limit in your game, or try a hardware encoder like Quick Sync or NVENC instead.

Tried it with different fps cap(60,30,40) , it had some minor impact but the video is still unwatchable, 'cause the video gets choppy. Here are my logs. Any advice?
