mass effect andromeda random hiccups/stuttering on sp gameplay

While not a satisfactory answer I managed to get most of the stuttering to go away when I used the Auto setting in the graphics options. It lowered my resolution to 900p but it did get better.

Yes:

By way of that I noticed you are using the 750 TI OC.
Which manufacturer version: PNY, EVGA, MSI, ZOTAC, ASUS, Gigabyte, Sapphire, or XFX?
Not all manufacture brands are equal.

The 750 TI OC Which -as pointed out is below the minimum specifications to run this game.
Has Mass Effect Andromeda ever locked up on you?
If not -then you must have a stout 550 TI OC to be able to endure the punishment this game can cause.

In my experience most Nvidia graphic cards of the 500 series usually don't handle loads well if the card is working above even 60*C.
Use MSI Afterburner program and look at the temps the graphics card is running.
If it is going over 60*C and jagging or stuttering the card most likely is trying to work to hard.

If that is the case you need to reduce graphics as soon as you can.
Again using MSI Afterburn and turn the Graphics card fan to 100% while gaming -most cards -unless otherwise told default to 30%.

Most people probably will not believe it but the lower you get the temp on the graphics card the faster and smoother the game will run.
Compared to maxing it out and actually frying the graphics card.

My last piece of advice is to lower all graphic settings to min values INCLUDING resolution.
I know it may not be ideal.
Yet in this situation you need to ask yourself:
Do you want to play the game or buy a $100-350 replacement card?

ONE LAST ITEM OF HELP:
You could also try reducing the scaling to 0.90... - this will significantly reduce load on the graphics card but at sharpness cost... as you take number lower gets more blurry.
0.90 seems rather to be in line with a standard game while anything higher seems to be going to high definition... don't advise 70 though... even I can barely take it.

I have that problem too But only (or mostly I'm not sure) on Nexus.

Thank you Vanguard. I had placed an order for EVGA 1080ti w/water cooling for $809 at NewEgg. I read only one bad review and it was that the watercooler unit had leaked. They hadn't processed the order yet, so I cancelled and changed it to an MSI 1080ti w/water cooling for $799. 16 reviews and all five eggs filled. It's going to be here in about 8-10 days. 

I run it with an i5-2500K and GTX770. Processor won't be an issue, but even my 770 seems to be fighting it. Might wanna consider getting a better GPU?

Game behaves a bit like yours. I can get decent FPS, but sometimes it'll stutter and it's not stable in any way. Our rigs just aren't exactly up there among the top of the line things anymore.

Going from 8GB to 16GB made a difference for me back in DAI, so it should do some good for MEA too.

Also something to have in mind - I believe the last patch (1.09) introduced decent optimizations in the graphic department. My GPU (1080Ti) used to reach 84C easily in MEA (playing at 1080p with everything at max settings) and I had to set a custom fan curve in order to keep the temperature at about 70-75C. It's a bit hot right now where I live, so the ambient temperature of the room is at it's peak for the year. After patch 1.09 I noticed my GPU to be mostly between 55-65C and with a bit less overall load. Graphic settings are the same as before and I visited the same areas as before. It might be something that works for specific systems and not for everyone, but 1.09 just might have made it easier for the GPUs to run the game.

What am I looking for? That it runs smooth?

Yes, it does. Most of the time. Stutters happen randomly. I'm not sure if it's an actual memory leak or certain transitions between cells. That the objects don't load properly or at a very slow rate.

Hmm I've never had an issue with my EVGA cards. Got a EVGA FTW 1079 and it's great. Not saying you're wrong maybe I'm just lucky.

I think the first I built had a GeForce 200 series and intel 4 I think lol. Ram may have even been DDR2.

I think the first PC I owned was a Power Mac back in '92. Can't remember the specs but I imagine they aren't good lol.

lol I had a nes, Sega Genesis and Sega Saturn then. Only thing I used my Mac for was Doom and Marathon. *sniff* I wish Bungie would see the light and re release that series for everyone.
