Low FPS in default scene of TD.... Why?

Postby Gtouch33 » Sat Jul 22, 2017 3:53 am

HI ALL!!!
why the computer with 40 GB RAM and with the video card NVIDIA GTX 760 has low fps in TouchDesigner default scene? FPS runs between 45-55 fps
Im working in TD more then 3 years but did not have such bad resaults in fps speed.
I had different computers and laptops.
Maybe codec?
Or videocard not optimized to work with TouchDesigner?
I would be very grateful if you help me)

The first thing I'd check is that you are running the latest drivers from www.nvidia.com. Is this a laptop or a desktop? I'd also check the power saving options to make sure you arn't running on a low-power setting

MY PC:

WIN 7 64 BIT i7 2.80GHz / 40 GB RAM /
NVIDIA GeForce GTX 760 DRIVER 382.53 (NEW) / DIRECTX RUNTIME FRESH
ON hdd C: more than 20Gb free space.

Power seems ok - top perfomance settings.

TOUCHDESIGNER 088 and TOUCHDESIGNER 099 the same problem.

The default scene FPS in 2 secounds changing in realtime from about 47 to 55(60) and back.
If I start default scene one more TD fps going more low about 35 to 50

Hi gtouch33,
when I look at the nvidia drivers site, it see the current driver for win7 geforce GTX 760 is 384.76, instead of the 382.53 you are using.

Thanks a lot for your help.
I install new driver NVIDIA )
Start TD and see that FPS looks better but not ideal/ Now FPS 51 - 60 in 2 seconds changing.
sometimes going to 45 ( its not good. :)

I will check other system parts. :!:

The plan B is to make one more computer with RADEON videocard with 1GB video memory on Sabertooth x58 motherboard.

The following is only applicable if you are using a laptop:
-In TD, place a Monitor DAT and see in the column "description" what video card TouchDesigner is using. if you see something like "Intel HD...." it means it is running on the onboard (slow) Intel GPU instead of your Nvidia GTX 760. Then you can try to set in your BIOS or in your laptop settings to set your Nvidia card as the default card.

WHEN I set 60 to 30 fps in TD the interval between max and min FPS changed to 28 - 30 FPS.
I dont understand now why.

I test in TD other FPS
and
10 FPS - is OK 10
55 FPS - is between 47 - 55
65 fps - 55 -61
100 fps and more - 51 - 61 fps MAX !
So I can use only <61 FPS
