Massive FPS drops on 2nd monitor

[Djay]

I have a really strange issue, when running winUAE 2.4.1 in a 1280 x 960 window on an external monitor (well, a 40 inch LCD 720p TV) connected by HDMI

every few seconds winUAE's CPU usage jumps up to around 166% and the FPS drops to around 30

however, if use directdraw instead direct3d its fine, i am guessing there are too many variables to work out why this happens...

my PC is okay.. quad core amd a3800, 12gb ram, geforce gt530 (2gb ram), dx11

will i suffer using directdraw as opposed to d3d?

any ideas?

Have you tried 2.5.0? Basically Direct3D needs a better PC, but except for filters you won't 'suffer' when using DirectDraw

[Djay]

haven't tried 2.5.0... will give it a go
so direct3d will not work on a 2nd monitor because of my spec?

it's fine on the primary monitor! but i never use filters anyway

thanks for you help TCD

Let's wait for Toni's answer then

DirectDraw vs Direct3d: depends on PC and drivers and everything. Use which one works the best.

But first check your display card's settings, it may have selected some 24p mode or something (instead of 50p/60p) when connected to a TV.

Attach winuaebootlog.txt (run winuae.exe when connected to a TV)

In the View menu of task manager, select "Show Kernel Times". If it's a driver issue, the red line in CPU Usage History window will reach high towards the top of the graph.

i have the latest nvidia drivers and dx 9/11 updates
the output to tv is limited 30hz, where as the pc monitor is 60hz

its funny cos i dont have this on ePSXe 1.8, fusion etc... but i know winUAE is more advanced and requires better performance etc

side note..

would be handy if winuae remembered window location in the configuration file not as the program? that way i could have one configuration for the monitor and one for the TV, but that a very specialist request


---
i will check task manager and produce a log in a sec

not a yule log of course

sorry i couldnt resist

You should get normal 50/60Hz from any HD Ready/Full HD TVs.
I guess 30Hz = interlaced 30Hz = not that good for Amiga.

What window?

ADDED: Include also 2.5.0 winuaebootlog.txt (and test it too)

sadly its not full hd, only 720p and a toshiba so its a bit shit, but it was a spare

UPDATE:
ok... tested it again, strangely defraging my HD and setting the screen to 1824x1026 has fixed it????

[Toni Wilen]

720p = "hd ready" and it is 99.9% sure that it will support 720p50 and 720p60 (It is 99.9999% if it has HDMI input)

You need to recheck your display driver control panel settings if there is no 50Hz available in winuae refresh rate selection menu. (and include winuaebootlog.txt)

At least ATI control panel needs clicking some checkboxes to enable 50p and 60p.

GUI window? 2.5+ has separate GUI position for windowed, full-window and fullscreen modes. (but it won't help if you need 2 different fullscreen GUI positions)

[Djay]

here is the winlog and a screenie of the Nvidia setting (the limit is 100% 30hz)

[Retro-Nerd]

Strange, never seen this 30Hz limit somewhere. Is it the same under "change resolution"? You said that you have a 720p TV, so 1280x720p would be the native and suggested resolution.

[Toni Wilen]

It seems you have forced single resolution (1824x1026?! 30Hz), all programs output that resolution, scaled if program selected something else.

It also says native resolution is 1920x1080, not 720.. This does not make sense

Log shows that normal 50Hz and 60Hz modes are available too.

[AmigaFriend]

You could create a custom mode in the Nvidia control panel. Create a 720p/1080 50Hz mode.

I don't use Nvidia for about 3 years now, but in 2009 I created a 100Hz mode for a second monitor which had a 120hz limit, that Win7 /default Nvidia modes would not get past from 85Hz. Maybe you have a similar problem.

[Djay]

further testing...

at 1920x1080 the screen needs to be resized to 1824x1026 and i only get 30hz for both... dropping down to 1280x720, which needs to be resized to 1216x684 i get 60hz

like i said its an awful 720p Toshiba LCD TV (the old(ish) bedroom TV)

here is a log at 1280x720...
