View Full Version : MadVR stutters TERRIBLY only in exclusive mode -- I have HIGH specs, shouldnt happen.

I dont know what to do about this -- I set the settings pretty high -- but i have a superpowered PC in terms of media -- its no SLI or crossfire desktop,

but its got 12gb DDR3 system ram, i7 processor, mega overclocked GTX660m running at 1.075 GHZ core clock, 2.6 GHz memory clock -- and that is ALL stable, done with modified bios/vbios.

I game on this machine frequently, and while it doesnt have the video ram required to max out textures and shaders in the most up-to-date games, it still can run the most demanding applications at at least moderately high settings -- usually only running into issues if I need more than 2 gigs dedicated VRAM or more shader cores (even with madvr, I extremely doubt I need more shader cores than a 3d video game) or overall just 2 graphics cards to support those settings.

so I KNOW I have more than enough power to be watching 1080p videos with decent amounts of filtering on. I'm not going crazy running the toughest filters either -- the ones that cause my card a little lag cause the same issue in windowed mode. the weakest links for me are no AVR receiver = all software decoding + analog 5.1 sound card and my monitor -- which is a shitty cheapo Vizio 1080p TV limited RGB, terrible gamma response (Can be corrected at great loss of color range) w/ poor contrast (this is getting upgraded first, then AVR)

I can ramp up the settings quite a bit, and in windowed mode it works beautifully no matter HOW I set it up -- no stutters, no loss of vsync no lag.

but the minute I set it to exclusive fullscreen it all goes to hell -- again, it doesnt seem to matter how the settings are set, it ALWAYS lags out, loses vsync, and causes me a bunch of errors/lag.

So Far I ended up just going borderless window mode and that seems to give me great quality with no lag -- again, I can't set like 2 renderers to be the most processor intensive without lag -- but thats not the issue -- the issue is that exclusive mode just plain doesnt work for me at all. with any settings.

there must be something Im doing or setting wrong -- im not used to so many options in a renderer, and i mainly aim for quality image reproduction while using DXVA or CUDA where available to offload work from the processor and accelerate it for the least lag -- so with moderate-high settings I doubt I should be having any troubles on this machine.

can anyone help a newb?

can you make a screen from the osd in fullscreen window mode.

is the 660>m< a typo?

Laptops are weird, my advice: Don't use exclusive mode. :D

There is nothing to be gained from exclusive mode if it isn't more stable. I don't use exclusive mode even though it works fine on my system because it doesn't work any better than the full screen windowed mode.

first off -- what is OSD -- tell me exactly what it is, and where to get at the window/page and I'll post a screenshot...

second:

no, its a laptop -- a gaming laptop -- the GFX card is HIGHLY overclocked, and this system has a strong processor and lots of ram. I basically use it as a home theatre and game console now that the battery doesnt hold charge long (its old) and its always plugged in. got a lot of external stuff to help like sound card, drives, etc. its got over a terrabyte of space too -- its not your average mid-range laptop -- its pretty strong, especially since I modded the bios/vbios and my clocks are over 400 mhz faster than stock

its more of a gaming desktop replacement than a regular laptop -- although the gfx card is the mobile version obviously. it is HUGE -- 18 inches I think, maybe bigger! its a little on the older side (the 660 was new when I bought it) so the battery is weak and its ALWAYS plugged in -- so its basically a desktop with a built in keyboard at this point.

so no, its not a typo -- it may be a laptop, but I promise you you'd never know it if you didnt SEE The actual unit -- its got so much power its crazy -- I play GTA V on almost maxed settings, crysis, anything you can throw at me.

the only thing that gets to me sometimes is it only has one card, and thus VRAM is maxed at 2GB -- no matter how much I overclock it I cant add more GDDR5 ram to the card.

also:
it DOES seem to run fine in any other mode, and there doesnt appear to be much increase in quality or anything with exclusive mode -- I know one of you says it doesnt matter and isnt important if its not stable --

but is there ANYTHING im losing out on by not using it?

if not, I dont really need it -- sure the loading/fast forward bar thingy has a nicer graphic -- but all the renderer changes I make seem to impact the picture the same either way.

if there isnt anything lost, I just wont use it.

There is NO difference in the image at all between full screen exclusive and full screen windowed. It is not a quality option in anyway.

OSD is On Screen Display, you can toggle it with CRTL-J.

Not unless you use 10 or 16 bit output which is only available in fse mode.
