Hello Community,

 

a few time ago I changed my system from a beta version of VPX8 to Rev 2051 (final), only with this system the ball- counter in JPS- tables works correctly. I think since that time I have stutter*) at some VPX8- tables. All other systems shows a smooth ball run. Question: is there any adjustment in the emulator that reduces the demand for graphic performance/power?

 

All suggestions will be appreciated!

 

Sincerely Christian.

 

*) the stutter is more than a rough ball, it happens seldom randomly and when it happens estimated 10 - 20 frames are lost and the fixed ball appears somewhere else.

Well, yeah ... there is a whole Prefs/Video page of graphics settings.

 

I suggest to start with:
- Check your Playfield monitor and Refresh are still correct/best
- Check your setting for Exclusive Full-Screen Mode (should be ON if playing and not tinkering)
- Evaluate best way to set Vertical-Sync (with your symptoms, try OFF first)

 

And in case VPX upgrade was just a coincidence ... check these same things in Windows (and/or Control-Panel for your video-card).

 

Maybe also be sure your B2S-Server is a recent version (like v2.1.4) and that all .directb2s files are "running as EXE". If not set properly, that will also make VPX tables  slow and laggy.

If you have an Nvidia card, you may try the VPX8 GL version. On some cards it may work better than the DX version. Maybe you loose a few fps, but it may be stutter free

On a previous VPX release i noticed half of the tables had stutters for me
After testing for a long time with various setting i was surprised that the issue was the Texture Compression video option

It surprised me because i always had it enabled because i didn't cared about high res textures (and more than often resize them manually by half to speed up loading) and thought the performance would just be better with it enabled, but in fact it was the opposite and it was actually the source of all the stutters i observed in the tables.
After "Compress Textures" disabled, i had no more stutters anymore.

So in case your stutter source is exactly the same as mine, give it a try in Preferences -> Video/Graphic Options -> UNCHECK "Compress Textures (performance)"

Hi

 

I don´t know about your hardware setup but, it would be a good information.

 

Below my hardware setup and video settings where any table run smoth.

 

CPU I7 3770

DDR3 16GB

MB 1155

PS 750 W

SSD 480 GB

W10

GPU GTX 1660 Super or TI 6 GB

 

3 Screen cabinet mode

 

2D 32" TV 60Hz 1920-1080 - BG

2D 15" monitor 60 Hz 1920-1080 - DMD

3D 42" LG TV 60 Hz 1920-1080 - Playfield

 

 

You can can set for your performance test.

 

I had some issues like yours with some scorbit tables. I need to disable sinc clock on script to fixed

 

VPX GL - 10.80 - 20151

VpinMame 3.6 - 1227

Backglass server - 2.1.5

DMD extensions 2.4.0

Dear Community, dear Tesla, JPS, Robsoie and Emanoel299,

 

thank you for all your ideas and your readiness to help.

 

To begin with my system:

 

CPU i5 - 7500

DDR4 8GB

MB ASUS H110M-A/M.2

PS 750W

SSD 240 GB

W7

NVIDIA GTX 750 Ti

 

2 screen cabinet mode

 

Panasonic TX39AW304 Playfield

Panasonic TX50AW304 BG

 

Front End PinballX with

FP

VP921

VP995

VPPM5

VPX6

VPX7

VPX8

 

all except a few VPX8 games all others runs without any hitch

 

I have two system: the cab with the TVs as mentioned above and lab 100% the same but with two monitors in portrait use. 

 

First I tried Tesla's suggestion, the Sync mode offers the settings:

no sync

vertical sync

adaptive sync

frame pacing

 

the initial state after 1st start of the emulator is frame pacing, I tried the other 3 and found that with "adaptive sync" the flaw is gone.

 

One question remains: how can I find which B2S server I use? I installed it 10 years ago and have forgotten this aspect.

 

Again thank you and have my best regards, Christian.

Not sure if your db2server has the information, since you tell me you haven't updated in 10 years

Depending on installation. You can just find B2SBackglassServer.dll and right click it. Then go to propertices -> details and "might" find a product version number.

Here it is in C:\Visual Pinball\Tables folder

Thank you for your setup information

Most of new VPX 10.8 table releases need more power GPU.

 

I have a machine with:

 

I7 2660

GPU GTX 1650 4GB

 

Some tables need to a "scpecifc table override" has follow:

 

 

I agree with Talamus.

At least for VPX 10.80 - 2051

It would be better update the auxiliar programm as BackglassServer and VpinMame.

But, I don´t know if they will work fine at W7.

1. Thanks for reporting back.

 

Yeah, the Control-Panel for my Nvidia GTX-1070 also has that same-named option, and I have used it there also before.

 

2. I'm running v2.1.4 from here:

 

https://github.com/v...l/b2s-backglass

 

I always un-register the old one before registering the new one.
