    I assume you have a model with the i5 processor? That is likely your bottleneck for game performance. Try setting your game to one of the low performance modes...

    Agree withbillsey . While your graphics should be capable of handling the load, the choke point for delivering this load also seems to be system memory. Unfortunately, your soldered 4GB mainboard may not be expandable unless it has a free RAM slot. You'd have to remove the base cover to check for this slot. I'm also gonna guess it has the i3 CPU which would further limit its game-playing performance even below the i5. Jack E/NJ

    I have the i5-8th one and I see in task manager it says 2 slots ram are used so I think no slot for more and the games run on high fps on HD resolution but when moving or turning or doing anything game start lagging and fps drops to 2 and 1 !

    And I don't think the ram is the problem because the same games are running with 4G ram on other laptops with lowest graphic card than mine

    You seem to have 2 X 2GB dual-channel soldered RAM. Your LCD screen also has a relatively slow refresh rate of 25-30 ms compared to 7-8ms for gaming laptops. While your graphics chip and screen can deliver high resolution images, they can't present them at the high FPS rates with the same high resolution the games demand. Accordingly, you really can't compare your FPS gaming performance with other laptops unless they have virtually the same hardware & software configurations.  Jack E/NJ

    I only need help in this why game like the Sims laggs and fps drop from high to 1 and 2 every mins ! That game don't require anything high ! Any game I set to low settings and the bar of VRam is like 900 mb/2000 and still lags when I move and fps drop ! No solve for this ?

    You can check task manager performance tab and resource monitors to see if any background processes are using too much CPU or HDD usage. You really should uninstall, not just disable, any non-Microsoft scanners. Jack E/NJ

    I noticed something i don't know is it okay or not but when I open game like fallout 4 the ram is okay used all but CPU don't exceed 20% in task manager is that okay ?

    >>>the ram is okay used all >>>

    What do you mean by this? It's not OK if all 4GB RAM is being used with nothing left over for temporary RAM storage. If not enough temporary RAM storage, then it uses virtual RAM on the HDD/SSD which is a lot slower.  Jack E/NJ

    I mean 97% of ram used but CPU usage is very low

    97% RAM usage is at a critical level. Only 3% surplus is not enough. Much slower virtual disk RAM has to be used if it sometimes goes to 100%. Is this steady 97% RAM usage or does it go lower when game playing? Jack E/NJ

    No it's steady 97%

    What happens to RAM usage when fallout is unloaded. Jack E/NJ

    Ram is running when I load it , it uses 97% and it down to normal 40% or more of system uses it

    1.6GB or 40% system usage seems about right. What game plays better than fallout? Load that game and see what RAM usage jumps up to.

    Dark souls 3 is better it uses 1.5G ram it's 95% now on 1920x1080 resolution and high graphics the game runs very smooth but from time to time it laggs because fps drops but in this game it don't happen alot

    Well, Souls has almost eight times better FastRAM surplus than Fallout (~25% vs ~3%). So it relies less on slower virtual RamDisk storage than Fallout But it still sometimes relies on RamDisk when temporary peak storage it needs exceeds the 25% FastRAM cushion. Since you can't add more FastRAM, you might improve speed of the virtual RamDisk if you add an m.2 nvme SSD especially if you're relying on an HDD now. Could be up to 10 times faster depending on the HDD in there now. Jack E/NJ

    You can play most games in 720p in medium or low settings. If you start to get random stuttering, its thermal throttling. That got fixed after I added extra cooling to the top of the laptop. (I just turned on pedestal fan towards the keyboard while gaming, it significantly improved the thermals and stopped the stutters.) LOL

    same laptop same cpu same gpu same ram same game, i have gta v with 60fps but it's too laggy, then i upgrade ram, ram solved my problem, you can use msi afterburner to check the temp, game'll be stutter when cpu >73 degrees Celsius, problem is: strong cpu strong gpu but low end ram, maybe it feels unfair

    First you need throttlestop and check the "disable and lock turbo power limits" box in FIVR, it'll prevent cpu from thermal throttling that means the cpu will ALWAYS running at full designed TDP(15w, you can't push it higher it will drop back to 15w)with no performance drop. You can undervolting the cpu to lower the heat or/and lowering TDP.

    Second you need to set the temp.limit in asus gpu tweak ii. Default value(mine is 77C) can cause the gpu suddenly decrease massive clock speed to keep temperature in limit and lead to stuttering, so you can push it up (I recommended not over 90C).

    So you'll get the full power of mx150 with NO THROTTLE.
    You can run GTA V @1080p high-very high preset with  around 40-50fps. If it start stuttering you can try pushing the gpu temp limit up.
    Note that your laptop will become VERY HOT I recommend you using the good cooling pad every time you playing the game and the thermal limits will reset every time at booting up you'll need to repeat it.
    PS. don't forget to plugged the charger every time you playing large game or high gpu load task, your battery will running out less than an hour or half and battery may wearing out faster.

    Finally, DWYOR!
    (Tested on Swift 3 SF314-54G, i5-8250u, MX150)
