So yeah recently I picked up 750ti, there seems to be some sort of consistent stuttering every time I play a game. Any game even something like league of legends, the screen just stutters for 1-2 secs, can be pretty game breaking. Not sure why it happens because my 550ti never had anything like that even when I played more graphically demanding games.

Also anyone playing bf4? Picked it up recently with china rising dlc, so looking for some peeps to play with!

Some ideas, may or may not be relevant

- Uninstall and reinstall the drivers
- Reseat the graphics card or your RAM
- If the 750Ti needs an extra power connector, plug that in
- Check the temperatures/clock speeds of the card. It may be overheating.
- Swap in your old card and check it doesn't happen

If you're absolutely sure it's the graphics card and you can't fix it, then RMA the card.

Yeah I will try the drivers and reseat it. But it does not have an extra power connector, seeing as apparently its pwoer efficient ones so doesn't need any extra power.

Your PSU is probably old or dying, or can't get enough power for the GPU , this happened before to me when I upgraded my GPU even though it wasn't a big upgrade, just that PSU worked better than the other for some reason.

Yeah but my graphics card is not actually connected to PSU like my old one was? There was no exterior plug to plug it in like in the old graphics card, so I just left it unhooked. It's just connected to mobo.

A PSU doesn't have an effect on a systems performance.
It is just to provide stable, clean, power.

What may have happened in your case is you moved cables when you installed a new PSU fixing your issue.

A graphics card typically can draw up-to 75 watts of energy from the PCI-E connector, which is carried via the motherboards power delivery systems which in turn is taken from the Power Supply unit, in general it's a cleaner form of power compared to grabbing it directly from most low-end and mid-range Power Supplies due to the extra voltage regulation that goes on in the motherboard.
PCI-E power cables that connect to a GPU provide an extra 75w of juice on average per cable, but the GPU will still draw the base 75w from the motherboard even in such instances.

I would suggest to do the following:
1) Clean out the dust on your CPU heatsink and fan. - If a CPU gets to hot it will throttle it's clockspeeds and voltages in order to prevent damage from being incurred, which impacts performance.
2) Check your power settings, make sure it's set to "balanced" in your power settings control panel. (Which can be found in the control panel on your computer.) - If it's set to "power saver" then your CPU's maximum frequency will be reduced.
3) Update Drivers/Reinstall Drivers and user Driver sweeper. - Contrary to popular beleif, nVidia drivers aren't gold plated, it has more lines of code than the Windows NT kernel, so issues are bound to crop up.
4) CCleaner. - Do a clean and a registry fix.
5) Check the clockspeeds of the GPU and make sure the fan is functioning and/or turn the fan up in the driver control panel.
6) Reinstall things like Visual-C runtime, Direct X 9 (Direct X 9 redist is probably easiest way to go.)
7) Check your task manager and see where your CPU time and Memory is being spent, sometimes it's just a rogue program/virus/other nasty that is simply gobbling up all your resources.
8) If you have an SSD as your main drive and it's nearly full, clean it up a bit. - Older SSD's have "garbage collection" which may not function correctly if the drive is full, which can provide erratic performance.

the problem is not the graphics card, the problem here is Battlefield 4 which is an absolutly unfinished and bad programmed game ;)

Cheers permalite, and DarkLink if you read the OP it was actually on LOL, not BF4, that was just a sidequest asking for some teammates

Do let us know if you still don't manage to sort it out! I have a relatively large repertoire of ways to fix such issues. :P

You sure?
There are serveral energy groups in the fuse box. Suppose you have multiple machine hefty machines active at the same time within the same group, this can effect power draw and in the end effect performance.
