lag

问题 I've noticed some strange behaviour that may or may not be specific to my system. (lenovo t430 running windows 8) With this script: import time now = time.time() while True: then = now now = time.time() dif = now - then print(dif) time.sleep(0.01) I get the following output (what I would consider nominal) with a browser open. However without a browser open I observe a severe per loop latency. Obviously this is counter-intuitive as I think anyone would expect better performance when you have

问题 I have write function in my functions module which looks like this def write(size, writing, color, x, y): font = pygame.font.SysFont("corbel", size) text = font.render(writing, True, color) D.blit(text, (x, y)) I imported this to my main module and created a function as follows in the main module def print_stats(): write(30, f"Red player's hp {player2.hp}", (200, 50, 50),10, 10) write(30, f"Green player's hp {player1.hp}", (50, 200, 50),10, 60) As long as i dont put print_stats() in the main

问题 I am following a tutorial series that is rather old on pyOpenGL and I am doing exactly as he does. However I am experiencing lag - I have AMD FX-6300 with 8gb ram, GTX-1050ti and files are stored on a flashdrive. I have read some places that using glBegin and glEnd cause issues? What should I use instead and how would I do it in this code: import pygame from pygame.locals import * from OpenGL.GL import * from OpenGL.GLU import * import random """ - A Cube has 8 Nodes/Verticies - 12 Lines

问题 So my game runs smoothly on PC (win 10), but lags on android phone (Mi 9T pro, SD 855, 6GB of ram). I don't mean that only sound lags, but graphics also. When I disable sounds it runs perfectly smooth (as it should). Yes I know that this question is asked and answered many times. And I tried all offered "solutions", but nothing helps. Tried using 22KHz samples, 44.1Khz, 48Khz. Tried adding 1 second of silence at end of each sample. Didn't help. I'm loading samples with this method: private

问题 We're using a Tabcontrol to display a number of items with rather expensive content, and the issue we're having is that as you iterate over the tabs (selecting them one by one), the responsiveness of the application becomes slower and slower. This behavior is unexpected as from what I understand, as the selected tab changes, the previously selected tabs content is unloaded first, so that you're only paying the price for one tabs content at a time. I've managed to simulate the behaviour with

问题 Closed . This question needs details or clarity. It is not currently accepting answers. Want to improve this question? Add details and clarify the problem by editing this post. Closed 4 years ago . Improve this question im trying to update table temp(F4) result from bottom to top. Is it while-loop every row and update can be order by? Thanks! 回答1: Assuming ROW is a positive integer then you can use (demo) WITH T1 AS ( SELECT *, MIN(CASE WHEN F4 <> 0 THEN CONCAT(FORMAT([ROW],'D10'),[F4]) END)

问题 I have a table with columns as product, txn_date and no_of_txns. One more column prev_day_txn added recently to the column. Data is something like below: Product TXN_DATE NO_OF_TXNS AA 1-JAN-19 100 AA 2-JAN-19 180 AA 3-JAN-19 290 With the new column added, data in the column should be populated with previous day's data. Output should be something like below: Product TXN_DATE NO_OF_TXNS PREV_DAY_TXN AA 1-JAN-19 100 0 AA 2-JAN-19 180 100 AA 3-JAN-19 290 180 I am trying to update the data using
