Speeding up 5.21

[Hquervo]

I cannot seem to turn Vsync off. I don't have a regidtry location ~/0000/settings/DirectX

Help!!!

[Gurm]

Well, I decided to double check.

I was right. I used the registry hack to turn off VSync. I can tell it's off, because there is some screen tearing in the one or two fast spots.

Anyway, for Quake3 1.08, demo 1, my scores are unchanged:

24.2fps with 5.15, 13.8fps with 5.21

All the settings are the same - I know they are, since all I did was swap out the ICD file (fresh install of 5.21 onto a fresh install of Win98 gave me 13.8, drop in the 5.15 icd and get 24.2).

So Ant, please - explain it to me. I'm not being mean, I just am curious as to how you propose to get this back up to speed!

Rags,

Don't patronize me. I know it came disabled... I turned it on.

GURM,

no patronizing going on here. VSYNC on or off affected only D3D, not OpenGL. No matter what you did, vsync only worked in D3D. Sorry, but that is the way it is. So, in effect, you will see no perf. drop in D3D with the new drivers, but will see a drop in OpenGL, since you want vsync enabled.

Err... ok rags yer confusing the hell out of me.

The hacks are, from the look of things, for D3D. Ok, fine.

How then, pray tell, do I disable VSync in OpenGL? I figured turning it off in the Quake3 config menu did the trick, perhaps I'm wrong?

- Gurm

P.S. And then why in God's name is Ant proposing the D3D registry hack to fix Quake 2 & 3, both of which are OpenGL only?

GURM -
Rags is correct. Try to follow-

In earlier drivers, vsynch was always disabled in OGL. There was no way to affect the vsynch in OGL. Period. The reg hack at that time would only affect D3D.

Now, with 5.21, vsynch can be enabled/disabled in OGL AND D3D. The same reg hack NOW affects both.

[Rags]

The reg hack had no effect on the drivers pre-PD 5.2x in OpenGL, because the Vsync was always disabled in OpenGL, no matter what anyone tried. Now, vsync is working in the new 5.2 drivers. So, you will see a difference in performance in BOTH D3D and OpenGL when disabling/enabling it, rather than just D3D with the "old" drivers.

Geeze, Kruzin, you must have taken lessons on how to be quick with that submit button from tylow.

Gurm is 100% right! The demo1 DOES drop a lot! In fact I got just like him a drop from 25.7 to 13.8fps! The slowdown can be seen in the open scene where there are lots of jumps. It literally crawls there!

That's all at 1024x768x32bit with everything on (trilinear, highest texture details, 32bit textures).

I did apply RegHack for disabling VSync. With VSync on it was 12.6 without it 13.8 (as I said). That is far cry from 25.7 I get with 5.13.

Strangely, demo2 got better. Went up from 26.4 to 27.0 in both VSync on and off... go figure.

r_swapinterval 0 or 1 produce EXACTLY the same results. deleting .cfg file as Haig suggested and setting the settings again doesn't change a thing.

The only good thing about 5.21 is that Rogue Squadron now works. Great job on that one! At 1280x1024 it rocks. I wish I could select 1600x1200...

BUT System Shock 2 is now broken! In the room where you choose between advanced and basic training the doors to the holos are screwed and you see some weird textures moving on them. It's perfectly fine with 5.13.

I didn't check Q2 - it might give 100fps for all I care - it's an old and stupid game with shitty graphics.

I'd summarize that DX compatibility improved, while OGL got worse, rather drastically.

P.S. Before I'll be declared incompetent, the reg hack was applied to 0000. I opened the .reg file in ASCII before applying it and followed to where it was adding the info. I checked - the info is there. The 5.13 drivers were first COMPLETELY uninstalled using _Matrox_ utility and then the 5.21 were installed. And since I'm getting what others are getting (same FPS precisely) we are NOT making this stuff up! Why would we???

I'm not questioning your compitance, I understand you are sure the reg hack went to 0000.

And I understand that you ran the uninstaller.

Just one question:
Is there a 0001, 0002, 0003 entry in that area, in addition to 0000?

[violentg]

does the mgatweak work for disabling the v-sync.if it does then i have no speed increase
so basically what are you guys saying you gained from old version(v-sync broken and off all the time) to this version(with v-sync turned off)
if you care about the other question just answer about the mga tweak

[KvHagedorn]

My only comment here is this: WHY SHOULD IT BE THIS DIFFICULT?? Even Ant was stumped at first, so don't tell me that every kid who plays with computers should be able to hack this problem with ease.

Haig: Just explain it clearly and put it in the control panel, please. No one should have to hack their registry or any of this other gobbledygook to turn vsync on and off, or to get their video card to perform as designed.

Now, if some people are turning vsync off but getting the same results, how do we explain this?

An easy way to enable/disable vsync and other options is to install Byron Montgomeri's g400tweak utility. Get it here ftp://ftp.cdrom.com/pub/3dfiles/utility/g400tweak.zip or http://ftp.telepac.pt/pub/3dfiles/utility/g400tweak.zip

What about playing with the refresh rate of your monitor? If your quake gives you, say, 75 fps on average, the optimal refesh rate should be 75 Hz, or a clean multiple of 75. This should allow you to approximate the game's full performance, with vsync on and thus without the tearing. Triple buffering should also be enabled, since with a second frame in store the refresh-frame-rate timing is not as critical as with only one. (Refer to http://www.entechtaiwan.com for more details.)

I havn't tried this for OpenGL (I do not use it, I do not play quake), but it should work according to all theory. In D3D, that I know, the rate of frames that actually appear on your screen can be much improved by setting the optimal monitor refresh rate - of course with vsync ON.

BTW: With the (D3D) games I play there's a performace gain of up to 15% with the 5.21 drivers, as compared to 5.15.

That's a good idea in theory, but in practise the performance will vary at lot.
