Watch Dog's sudden Frame rate drops or skips or stuttering ?

Aritrya · Jun 13, 2014

While playing Watch Dogs, i get a solid 70-80 FPS indoors or ally ways, 50-60 Fps normal city areas or running around , 45-50 FPS extremely crowded and graphically intense areas. Though it runs extremely smooth 90% of the time, but at times it suddenly gives a FPS drop or skip that causes a jerk, last for like half a sec then again runs smooth.
My game settings are set high ( not ultra ), Ambient Occlusion to HBAO+low, and Temporal SMAA.
I have used Geforce Experience to Optimize the game according to the given profile. Playing in screen resolution 1024X768. My Graphics Driver is updated, System is scanned for virus everyday, hard disk & Registry is defraged everyday and checked for errors. I close all the back ground apps when playing, set the windows theme to basic, switch turbo mode on in Tune up & set the PC properties in performance from control panel.

My system Config : Intel Core i5 3450 4cores 3.10GHz 3.50GHz turbo, Zotac Geforce GTX 660 Synergy Edition, 8Gb RAM.

That's normal for high demand games. BF4 players are complaining all the time.

A GTX660 is not a high end card.

How can you play at that resoloution :|. I don't think the issue you're having is on your end I bet a lot of people get this same issue new games always have issues. Just wait for a patch. On a side note there is 0 reason to clean your registry daily weekly maybe but not daily. There is also no reason to defray daily it'll harm more then do good when you do it that frequently

GTX 660 Synergy is 27% better than the recommended GFX card in that particular settings and Resolution.

Watchdogs currently has a few DRM issues where it it will periodically perform some kind of scan that causes a lag spike in the game on mid to lower mid CPU's

In watchdogs, the renderer is single threaded (generally using the first core) (thread nvwgf2umx will generally fully occupy a single core, generally during the lag spikes a previously idle MSVCR100 thread will become active and cause a corresponding drop of CPU usage of the render thread, and the end result during gameplay is a large drop in framerates in addition to a large drop in GPU usage. (it goes away after a few seconds), if you have the other issue extremely frequent large lag spikes (e.g., going down to single digits very frequently while driving) then the game is likely starved for video memory and the dumping of unneeded textures and loading of new ones causes a huge performance bottleneck which will also cause a drop in GPU usage while new data is loaded to video memory)

Other than that, there are certain bugged areas in the game where certain objects will not 100% touch, when you find those and are able to see through some of the map, this causes the game to render a lot more than it normally will and you will notice a huge drop in framerate and higher video memory usage (and lower GPU usage, and thus a lag spike that doe snot go away as long as you are looking at that gap) I only found one spot in the game that has that issue (don't remember the exact location, but it is at a gun store near one of the train lines)

(Not sure how much help it will be, but disabling aero will usually free up a few megabytes of video memory)

Again......GTX 660 Synergy is 27% better than the recommended GFX card in that particular settings ( High, not Ultra ) and Resolution ( 1024X768, not 1920X1080 ).

Thanks for explaining it! was a big help.
