Thanks for the suggestion. Better yet, I found a solution to the input lag problem that comes with vsync. The trick is limiting the frame rate to just below the refresh rate when vsync is enabled. If the frame rate would be equal to or greater than the refresh rate when vsync is enabled, there will be input lag.

The trick also works with other games.

Hey,

My monitor's native refresh rate is 60 Hz. I'd like to achieve perfectly smooth motion in-game by setting the fps to exactly 60. I can't use v-sync because it causes slight input lag which is very irritating (disabling triple buffering would help that but it can't be disabled for DirectX within the current ATI drivers).

Doing this is not currently possible via conventional means, as the game has a minimum sleep of 1 millisecond. The fps limit is defined by a minimum duration between frame updates, which is an integer value (Min Frame Time). Being an integer it doesn't allow fractions and for that reason limits such as 58 and 62 are available but not 60.

Of course I could just let the game render at the 200fps speeds and forget about it, but it does not feel right that the hardware is rendering a lot of frames that are not displayed. It's kind of a waste, you know.

I'd like to know if anyone has pondered on this kind of thing and perhaps found some solution, maybe using some external software to limit the fps, and how that has worked out. Thanks!

Quote from HugeF1 :

I do what I like, and I don't want or need the likes of you to tell me what to do. I raced at BW the other night. I crashed lots, took people out and all of it my fault. Not ONE person was immature or stupid enought to call me a noob.

You can hopefully do whatever you find pleasing, but respect for others should come first. This should become obvious along with social maturity.

And, "noob" or not, you can always use the prediction mechanism built into your brain to decelerate early when it seems necessary to avoid a crash. I think it's mostly a case of common sense than skill.

You have to unlock the game again after patching. It's normal.

Thank you! Greatly appreciated.

I drove a few laps and I really enjoy the new feel of it. Very solid and controllable. BF1 is surprisingly easy and fun to drive for a BF1 newbie. Lovely speed on the straights. :-)

neo force KP61: Yeah, extract the archive into your LFS folder and allow it to overwrite everything.

Quote from JTbo :

Racing is waiting, not believing me? Well, but it is, you need to wait proper place to overtake for example, of course you can be n00b and push trough other cars to T1 but that is not racing, that is hotlapping and ignoring others completely.

Yeah, patience is a profitable virtue in racing, but waiting for a good place to overtake differs from waiting for the race to start. I don't have the patience to wait 5 minutes for the race to start, but I won't throw stupid stunts on the track. I most often win not because of speed but because of patience.

Quote :

I can wait 30mins to have 30mins of good racing without some ppl pushing trough impossible space causing mayhem.

That's fine. Some people think that way. When I want to race, I want to race now and not after 30 minutes. After 30mins I probably have something else to do.

Quote :

Also because nobody don't like waiting they make sure they don't crash, they start really racing.

Because nobody likes waiting, nobody joins the server.

Quote :

However I find it frustrating that there is not many LFS'ers that really know what racing is and how to race properly,

That's no reason to cause inconvenience to well-behaving people.

What's the problem if mid-race joining is enabled on some (most) servers? Don't join those servers if you don't like it. Your extremist attitude isn't fun. How about banning everyone who make mistakes? They're surely not professional enough. See you after 10 years of training, huh? ;-)

I think it's better to keep things this way. The game is about racing and not waiting.

It can be time consuming to get the ati card running so if you've got spare time and interest in the matter, I welcome you to give it a shot. :-) Otherwise it might not be worthwhile...

I also have a Windows partition for Linux-incompatible stuff. I'm trying to get rid of Windows because I prefer freedom over uncertainty. Currently only games and some music composition software preserve the existence of the Windows partition. I hope I could fully migrate to Linux at some point.

Thanks for your replies!

avellis, caught some new ideas at the rscnet forums. Thanks for pointing me there.

the_angry_angel, well I'm glad it works for you at least. :-) The ati driver should be properly in place also from wine's viewpoint because quake3-based win32 games under wine report correct renderer info in the console. As I told before, natives run perfectly well so I'd say with good confidence it's 100% ati code running the 3d show.

I installed Wine 20050725 (the newest deb I could find) which didn't affect performance. 0830 has been released recently but the debs aren't available yet. I'm gonna grab the newest wine and cedega sources from cvs and compile them for this k8 instruction set to see if that helps - although I'm pretty sure that won't solve anything. The problem is likely caused by numerous hard-to-spot incompatibilities and not just one defective component.

Thanks.

Update: Newest cedega segfaults at startup displaying a black screen, wine shows no performance improvements. It would be interesting to know if wine performance issues are more frequent among atians than nvidians. It's a known fact that nvidia's linux driver is better.

Hey, I was wondering if anyone has come up with any tweaks that improve fps performance under GNU/Linux. Currently, fps jumps between 10 and 120, depending on track surroundings and the number of cars on the screen. The game runs perfectly well under Windows XP on this computer.

TransGaming Cedega seems to crash right when 3d graphics are to be drawn (only with lfs) so I don't know how well it would perform fps-wise over the free Wine package.

All gfx detail settings in lfs are at minimum. Screen resolution doesn't seem to matter. I have already disabled cpu frequency scaling (cpu power saving) as it seems to cause fps problems under Wine.

I'm running Ubuntu Hoary with Wine 20050310. I shall experiment with some bleeding-edge cvs version of Wine asap. My gpu is Radeon 9800 Pro, fglrx is 8.16.20. Cpu A64 3200+ @ 2,2GHz. Linux 2.6.13 with K8 instructions (custom build with desktop-friendly settings). To clarify, the OS is 32-bit, not 64-bit. Xorg is 6.8.2.

Native games like UT 2004 run very well on my configuration.

Any hints or suggestions?
